For conventional perpendicular recording media of saturation magnetization M/sub S/ and grain volume V, the ratio of the stabilizing energy barrier /spl Delta/E to the switching field H/sub S/ is /spl xi/=2/spl Delta/E/(M/sub S/H/sub S/V)=1, in contrast to a value of 2 for the case of anisotropy axes tilted at an angle of 45/spl deg/. This means only half the possible resistance to superparamagnetism is gained; it makes writability a serious problem for high density perpendicular media when a large anisotropy is used to compensate decreased grain size. To address this problem, an exchange coupled composite perpendicular recording media has been proposed that increases /spl xi/ by a factor of two, as in 45/spl deg/ tilted media, but reduces some of the difficulties, particularly in fabrication.

Micromagnetic modeling was performed to verify that antivortex states interacting with vortex states can play a crucial role in M dynamics in confined and semi-continuous model systems. Results offer comprehensive insights into the understanding of the static or dynamic properties of M reversal processes, and new features or more details of domain and domain-wall structures observed in continuous real films.

A boundary meshless method (BMLM) for transient analysis was presented. This method combined a point interpolation method for construction of spatial shape functions for the governing equations. The spatial shape functions satisfied the Kronecker delta function and the essential boundary condition can be directly imposed on the boundary. Eddy current distribution and eddy current density on symmetry axis were also given using the proposed method. The results all proved that BMLM is an effective technique to analyze the transient eddy current problems.

The crystal structure and magnetostrictive properties of Fe-Al thin films prepared by ion plating process were investigated. Film composition, structure, magnetization and in-plane magnetostriction were obtained by energy dispersive X-ray spectroscopy, X-ray diffraction, vibrating sample magnetometer and cantilever method respectively. The film showed higher magnetostrictive susceptibility and larger magnetostriction at low magnetic fields.

The power loss analysis was carried out for Ni-Cu-Zn ferrite samples with different content of NiO and ZnO. The power loss, Pc/spl nu/ decreases monotonically with increasing temperature and attains to a certain value at around 100/spl sim/120 degrees Celsius. The frequency dependence of Pc/spl nu/ can be explained by Pc/spl nu//spl sim/f, and n is independent of the frequency, f up to 1 MHz. The Pc/spl nu/ decreases with an increase in ZnO/NiO. The Pc/spl nu/ was separated to hysteresis loss, Ph and residual loss, (Pc/spl nu/-Ph). The temperature characteristics and compositional dependence of Pc/spl nu/ can be attributed to the Ph, while (Pc/spl nu/-Ph) is not affected by both temperature and ZnO/NiO. By analyzing temperature and composition dependence of Ph and initial permeability, u/sub i/ following equations could be formularized. u/sub i/u/sub 0/ = I/sub s//sup 2//(K/sub I/ + bs/sub 0/l/sub s/) (1), Wh = 13.5(I/sub s//sup 2//u/sub i/u/sub 0/) (2), where u/sub 0/ is permeability of vacuum, I/sub s/ saturation magnetization, K/sub I/ anisotropy constant, s/sub 0/ internal heterogeneous stress, l/sub s/ magnetostriction constant, b unknown constant. Wh hysteresis loss per one cycle of excitation (Ph = Wh*f). Steinmetz constant of Ni-Cu-Zn ferrites, m = 1.64/spl sim/2.2 is smaller than the one of Mn-Zn ferrites, which suggests the difference of loss mechanism between these materials.

Polycrystalline samples of Zn/sub 1-x/In/sub x/Co/sub 0.075/O (0.010/spl les/x/spl les/0.020) diluted magnetic semiconductors were prepared by the rapid oxalate decomposition technique. Phase purity is analyzed by means of X-ray diffraction technique and structures are refined by Rietveld refinement technique. Bulk conductivity of the polished pellets was measured by two-point probe technique at 295 K. Magnetic properties were analyzed with magnetic property measurement system. Samples show paramagnetic behavior and Curie-Weiss fitting at high temperature range gave effective magnetic moment of Co ions. Magnetization behavior caused by applied magnetic field was also investigated. High itinerant carrier concentration was achieved but no ferromagnetism was observed in the samples.

The demagnetizing energy being required in obtaining a demagnetizing factor for a single-domain particle of nonellipsoidal shape, with spontaneous magnetization in an arbitrary direction is investigated. The concept of demagnetizing factors plays an important role in theoretical interpretation of many ferromagnetic phenomena. It was found that demagnetizing energy per unit volume of a uniformly magnetized cube is exactly the same as for a uniformly magnetized sphere and independent on the magnetization direction. The body considered is that with two threefold rotation axes.

A new combination process which consists of rectangular shaped nozzle with single output and electromagnetic stirring (EMS) is considered to obtain high inner quality steel during continuous casting process. The usefulness of this process is evaluated by means of magnetohydrodynamic (MHD) calculation. The proposed process with the rectangular shaped nozzle and EMS at meniscus seems to realize both some velocity at downward flow diffusion and meniscus flow.

In this paper, a novel synthetic route is reported for magnetic silica nanotubes (MSNTS) via a sol-gel method by using nanosized calcium carbonate (CaCO/sub 3/) nanoneedle as a sacrificial template, and Fe/sub 3/O/sub 4/ nanoparticle and tetraethoxysilane (TEOS) as precursors. The samples were investigated by field scanning electron microscope (FESEM) and transmission electron microscope (TEM). Magnetic properties were measured with a Quantum Design MPMS-5S SQUID magnetometer. The diameter of nanoneedles ranges from 50 to 80 nm. The length of the nanoneedles is about micron size. After the sol-gel coating and weak acid etching, silica nanotubes with a shell of 20-40 nm were obtained. Electron energy dispersive X-ray analysis (EDS) indicated that all CaCO/sub 3/ nanoneedles were removed during the etching. The nanoparticles were randomly embedded inside the shells of silica nanotubes. Zero-field-cooled (ZFC) and field-cooled (FC) magnetization data in the temperature range of 10 to 300 K were acquired. A field of 100 Oe was applied as the sample was cooled to the lowest temperature and the magnetization was measured as the sample was heated from 5 to 300 K in the field of 100 Oe. The ZFC curve shows a maximum at 291 K, which is the blocking temperature (T/sub B/). MSNTS exhibit superparamagnetism and ferromagnetism above and below the blocking temperature. It is therefore expected that MSNTS can be exploited as delivery vehicles and supports in bioscience applications.

The magnetic core materials for motors have been mostly limited to non-oriented electrical steels of which crystallographic texture is almost random, although there is a possibility to greatly improve performance of motors by the use of steels with textures such as {100}<001>.The purpose of this research is to investigate how the performance of motors can be improved by the use of such a textured material by building actual motors using a doubly oriented electrical steel that has a strong {100}<001> texture. This key material in this investigation has been prepared by the process so-called oxide-separator-induced decarburization that has been found recently.
