We fabricated two kinds of cantilever actuator and a traveling machine by using magnetostrictive Tb-Fe and Sm-Fe thin films on a polyimide substrate. No power supply cable is required for their actuation, because they are driven by an external magnetic field. The magnetostrictive cantilevers exhibited a large deflection in low magnetic fields. Their unique characteristics suggest that magnetostriction can be used as the driving mechanism of microactuators.

A bulk Fe 84 Nb 7 B 9 alloy was produced by extruding amorphous powder at temperatures (T e ) between 653 and 723K, at pressures (P e ) between 824 and 1208 MPa, and at a speed (V e ) of 5 mm/s. The subsequent annealing of the extruded bulk alloy for 3.6 ks at temperatures between 873 and 973K resulted in the formation of a (for the most part) single bec phase, with grain sizes near 10 nm. The bulk alloy, extruded at a P e above 1000 MPa, has a high relative density of 99%. The soft magnetic properties are better for bulk materials extruded at lower pressures, and the bulk alloy extruded at T e =698K and P e =870 MPa exhibits a magnetization (B 800 ) of 1.40 T, a permeability of 1123, and a coercive force (H c ) of 47 A/m, values which are inferior to those of the bec ribbon alloy (1.49 T, 22000, 8 A/m). The difference between the soft magnetic properties of the bulk material and the ribbon forms is presumably due to the inhomogeneity of the microstructure, oxidation of the powder, and the remainder of a higher internal stress in the bulk alloy.

Pen recorders with moving-coil-type linear dc motors (LDMs) have already been used in practical applications. However, an optimal design has not yet been established within the dimensional limitations of such devices. This paper provides a guideline for optimum design through characteristic analysis of pen recorder units, using a thin, long-stroke LDM. In the LDM, the flux density acting on the coil is equal to the flux density in the gap. The LDM thrust constant consists of N, 1 and B, where N and 1 are known as design values. However, B is determined by the magnetic design. The finite element method (FEM) is used to analyze the three-dimensional magnetic fields of the magnetic circuit, which consists of a permanent magnet and yokes.

The magnetic inductance obtained by feeding a current through Fe-Co-Si-B amorphous wires with near-zero negative magnetostriction was measured at frequencies between 0.5 kHz and 13 MHz. It was found that an as-quenched Fe-Co based wire (Co94) having nearly zero magnetostriction (of the order of ¿10¿7) exhibited a bamboo-shaped domain structure and an inductance of 9 ¿H/cm at frequencies up to 10 kHz. It was also found that the magnetostriction of the same Fe-Co base wire was shifted in the positive direction by annealing and that the bamboo-like domain structure of the wire with near-zero magnetostriction acquired a maze-like domain structure. A more Co-rich wire (Co95) was fabricated, to take account of the change in magnetostriction. It is shown that the more Co-rich wire retains the bamboo-like domain structure after annealing and exhibits a fairly large inductance of 60 ¿H/cm at 1 kHz and 20 ¿H/cm at 10 kHz; the latter figure is 2.3 times larger than that of a so-called cross-inductor.

An improved technique was developed for measuring the attenuation constants of magnetoelastic waves in amorphous wires under an arbitrary magnetic field. Measured attenuation constants in an asquenched, a wire-drawn, an annealed, and a drawn and then annealed Fe-Si-B wire were determined as a function of the magnetic field applied to the sample wires. An extremely large value of the attenuation constant was observed in the annealed wire under no magnetic field. The value decreased rapidly when a magnetic field was applied to the wire. We also showed that the dependence of the attenuation constant on the magnetic field can be used to control the amplitude of the magnetoelastic waves.

The magnetic properties of Fe-M-O (M=Zr, Hf≫ films with high electrical resistivity, prepared by the rf magnetron sputtering technique in an Ar+O2 atmosphere, were investigated. In the as-deposited state, low coercivities (Hc) in the range 30 to 100 A/m were obtained for Fe-Hf-O, and 160 to 240 A/m for Fe-Zr-O, in the composition range characterized by an O/M ratio of between 3 and 4. After annealing under optimum conditions in an external field of 160 kA/m, the results obtained for Fe54.9Hf11O34.1 and Fe65.3Zr8.9O25.8 included a saturation magnetization (Bs) of 1.2 T, an Hc of 64 A/m, and a ¿ at 100 MHz of 1600 for the former, and a Bs of 1.3 T, Hc of 73 A/m and ¿ at 100 MHz of 1000 for the latter. Further, the electrical resistivities of the films were much higher than those of known metallic soft magnetic films.

Ni x Fe 1-x /Cu multilayer films were prepared on glass substrate by magnetron sputtering. The dependence of the giant magnetoresistance on the composition and temperature were investigated. When the composition of the magnetic layer was varied, the MR ratio exhibited peaks at x=0.6 to 0.7 at 4.2K, and at x=0.7 to 0.8 at 300K. As the temperature was raised, the MR ratio of multilayer films with larger magnetic moments decreased more rapidly than that of films with lower magnetic moments. This result can be explained consistently in terms of the spin fluctuation model proposed by Hasegawa.

Iron-chromium magnetic alloy has received attention recently as a soft magnetic material that can be used in an alternating magnetic field. A technique for improving its properties by increasing the aluminum content was studied. An increase in its amplitude-relative permeability in an alternating magnetic field occurs when the aluminum composition is increased to 5% from 1%, in spite of a decrease in the amplitude-relative permeability in a direct magnetic field. The increase in aluminum content causes smaller changes in the hysteresis curve and amplitude-relative permeability with the alternating magnetic field frequency and the ring specimen thickness. As expected, these phenomena are dependent on the electrical resistivity of the material.

A new phase-modulation device with simple structure and high reliability was constructed using a short amorphous wire. A high-frequency ac current (carrier) and a signal current are simultaneously passed through the wire, which undergoes the large Barkhausen effect when the circumferential flux changes. Highly linear modulation characteristics were obtained up to 0.67¿ using a triangular-wave ac current, passed through tension-annealed wire 30 ¿m in diameter and 5 mm in length. This simple yet reliable phase modulation device is expected to find applications in the field of factory automation communication networks.
