Ab-initio study of electronic and magnetic properties of MnRuZ/MgO (001) heterojunctions (Z= Al, Ga, Si, Ge)
Tufan Roy, Masahito Tsujikawa, Masafumi Shirai
Using first-principles calculations, we studied MnRuZ (Z=Al, Ga, Si, Ge) and their heterojunctions with MgO along (001) direction. All these alloys possess HgCuTi-type inve…
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…
