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…
Magnetic tunnel junctions with a B2-ordered CoFeCrAl equiatomic Heusler alloy
Tomoki Tsuchiya, Tufan Roy, Kelvin Elphick +8
The equiatomic quaternary Heusler alloy CoFeCrAl is a candidate material for spin-gapless semiconductors (SGSs). However, to date, there have been no experimental attempts at fabri…
MnVAl Heusler alloy thin films: Appearance of antiferromagnetism and an exchange bias in a layered structure with Fe
Tomoki Tsuchiya, Ryota Kobayashi, Takahide Kubota +5
MnVAl Heusler alloy films were epitaxially grown on MgO(100) single crystal substrates by means of ultra-high-vacuum magnetron sputtering. A2 and L2 type MnVAl order wa…
