We present general expressions for the magnetic transition rates in electron paramagnetic resonance (EPR) experiments of anisotropic spin systems in the solid state. The expressions apply to general spin centers and arbitrary excitation geometry (Voigt, Faraday, and intermediate). They work for linear and circular polarized as well as unpolarized excitation, and for crystals and powders. The ex...

Nanoparticles of iron-cobalt have attracted great interest in recent years because of their unique physical and chemical properties because of their industrial importance in preparing magnetic recording materials, pigments, catalysts, etc. With an objective to develop magnetic materials with high saturation magnetization Fe-Co nanosysytems were synthesized by method of chemical reduction reacti...

Single phase and nanosized powders of high-entropy (BiSbSe1.5Te1.5)1-xCux compound with x=0; 0.3, 0.6 were synthesized by using soft chemistry approaches. Owing to its low thermal conductivity, this is promising for thermoelectric applications. The used prepare bulk samples totally suitable testing properties.

It is well known that in recent years magnetic materials have received increased attention due to their properties. For this reason a significant number of patents that were published during the last decade are oriented towards synthesis and study of such materials. The aim of this work is to create and study ferrite nanocrystalline materials with spinel structure, using sol-gel technology with...

In order to improve the recording efficiency in current perpendicular recording media, it is important to reduce the distance from the head to soft underlayer. In this paper, a soft magnetic intermediate layer is proposed to partially replace the presently used Ru intermediate layer. The new soft magnetic intermediate layer serves two purposes, which are as follows: 1 to decrease the thickness ...

2014 The paramagnetic Fe(I) electron reservoir sandwich ~5-C5H5Fe(I) ~6-C6(Me)6, its oxidized monocationic diamagnetic form and related diamagnetic ~5-C5H5Fe (cyclohexadienyl) complexes have been studied by Mössbauer spectroscopy on powders and aligned crystals. Spectra under high magnetic field were recorded for powders. On the basis of X-ray data I.E.H.T. MO calculations were performed and ga...

Abstract We present a strategy for the design of ferromagnetic materials with exceptionally low magnetic hysteresis, quantified by coercivity. In this strategy, we use micromagnetic algorithm that have developed in previous research and which has been validated its success solving “Permalloy Problem”—the well-known difficulty predicting composition 78.5% Ni lowest coercivity Fe–Ni system—and in...

In contrast with amorphous alloys, nanocrystalline soft magnetic materials show improved thermal stability and higher soft magnetic properties. The nanocrystalline soft magnetic composites are usually fabricated by partially crystallizing from parent amorphous alloys. This paper reports our experimental observation on the sequence of crystallization in metallic glass under a high magnetic field...
