Abstract
We report on the magnetization reversal dynamics of Ni-rich Ni1-xFex electrodeposited nanowires. Ordered arrays of Ni1-xFex nanowires with varying Ni and Fe composition (in percentage) are synthesized using the pulsed electrochemical deposition method through porous track-etched polycarbonate templates. The shape and size of the nanowires are investigated by Scanning Electron Microscopy (SEM). X-ray diffraction (XRD) analysis shows the polycrystalline nature of the nanowires, having an average crystallite size of ∼6.9 nm. Structural characterization is carried out to establish the material and structural property by TEM, while the chemical composition is analyzed with Energy Dispersive X-ray analysis (EDX). Atomic Force Microscopy (AFM) and Magnetic Force Microscopy (MFM) are employed to investigate the topography and magnetic domain structures of these nanowires. The vibrating sample magnetometer (VSM) technique has been carried out to measure the magnetic hysteresis loops for the Ni1-xFex nanowires with different compositions embedded in the template. The hysteresis loops measured with an external magnetic field applied parallel and perpendicular to the axis of the nanowires show a clear difference in the shape and the coercive field, indicating the effect of texture and iron content in these samples. Micromagnetic simulations (OOMMF) are performed to comprehend the experimental results and to make a correlation with the magnetization reversal mechanism in magnetic nanowires.
期刊介绍：
Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged.
A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions.
The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
