Bias sputtering of granular -FePt films with hexagonal boron nitride grain boundaries
Chengchao Xu, B. S. D. Ch. S Varaprasad, David E. Laughlin +2
In this paper, we present an experimental study of -FePt granular films with crystalline/amorphous boron nitride (BN) grain boundary materials for heat assisted magnet…
The effect of adding magnetic oxide as grain boundary for HAMR
Bing Zhou, B. S. D. Ch. S. Varaprasad, Zhengkun Dai +2
Grain-to-grain Curie temperature (Tc) variation in the media reduces signal-to-noise ratio due to its contribution in transition jitter noise, especially when average grain size is…
High spin polarization and large spin splitting in equiatomic quaternary CoFeCrAl Heusler alloy
Lakhan Bainsla, A. I. Mallick, A. A. Coelho +6
In this paper, we investigate CoFeCrAl alloy by means of various experimental techniques and ab-initio calculations to look for half-metallic nature. The alloy is found to exist in…
Spin gapless semiconducting behavior in equiatomic quaternary CoFeMnSi Heusler alloy
Lakhan Bainsla, A. I. Mallick, M. Manivel Raja +6
Spin gapless semiconductors (SGS) form a new class of magnetic semiconductors, which has a band gap for one spin sub band and zero band gap for the other, and thus are useful for t…
All-optical control of ferromagnetic thin films and nanostructures
Charles-Henri Lambert, Stephane Mangin, B. S. D. Ch. S. Varaprasad +8
The interplay of light and magnetism has been a topic of interest since the original observations of Faraday and Kerr where magnetic materials affect the light polarization. While…
Investigation of the quaternary Fe2-xCoxMnSi alloys by structural, magnetic, resistivity and spin polarization measurements
Lakhan Bainsla, K. G. Suresh, M. Manivel Raja +1
Effects of the Co substitution have been observed on the structural, magnetic and magneto-transport properties of Fe2-xCoxMnSi alloy. Curie temperature (TC) and saturation magnetiz…
