Tracing magnetic atom diffusion with annealing at the interface between CoMn alloy and MnGa layer by X-ray magnetic circular dichroism
Jun Okabayashi, Kazuya Z. Suzuki, Shigemi Mizukami
The magnetic atom diffusion at the interface between CoMn alloy and MnGa layer with annealing is studied using x-ray magnetic circular dichroism (XMCD) analysis. We found that the…
Giant effective damping of octupole oscillation in an antiferromagnetic Weyl semimetal
Shinji Miwa, Satoshi Iihama, Takuya Nomoto +8
A magnetic Weyl semimetal is a recent focus of extensive research as it may exhibit large and robust transport phenomena associated with topologically protected Weyl points in mome…
Parity-controlled spin-wave excitations in synthetic antiferromagnets
A. Sud, Y. Koike, S. Iihama +3
We report in this study the current-induced-torque excitation of acoustic and optical modes in Ta/NiFe/Ru/NiFe/Ta synthetic antiferromagnet stacks grown on SiO2/Si substrates. The…
Lattice Softening in Metastable bcc CoxMn100-x(001) Ferromagnetic Layers for a Strain-Less Magnetic Tunnel Junction
Kelvin Elphick, Kenta Yoshida, Tufan Roy +8
In spintronics, one of the long standing questions is why the MgO-based magnetic tunnel junction (MTJ) is almost the only option to achieve a large tunnelling magnetoresistance (TM…
Structural and magnetic properties of epitaxial films of CoIrMnAl equiatomic quaternary Heusler alloy designed from first-principles calculation
Ren Monma, Tufan Roy, Kazuya Suzuki +4
MgO-barrier magnetic tunnel junctions with half-metallic Heusler alloy electrodes attracted much attentions for spintronics applications. However, a couples of issues related to ma…
High tunnel magnetoresistance and magnetism in metastable bcc CoMn-based magnetic tunnel junctions
Kazuma Kunimatsu, Tufan Roy, Jun Okabayashi +7
Co-rich CoMn alloys have hcp or fcc disordered phases and those ferromagnetic orderings are significantly deteriorated with increasing Mn concentration in bulk. On…
