Theory for Tunnel Magnetoresistance Oscillation
Keisuke Masuda, Thomas Scheike, Hiroaki Sukegawa +3
The universal oscillation of the tunnel magnetoresistance (TMR) ratio as a function of the insulating barrier thickness in crystalline magnetic tunnel junctions (MTJs) is a long-st…
Fully epitaxial fcc(111) magnetic tunnel junctions with a Co90Fe10/MgAlO/Co90Fe10 structure
Jieyuan Song, Thomas Scheike, Cong He +5
Magnetic tunnel junctions (MTJs) with bcc(001)-type structures such as Fe(001)/MgO(001)/Fe(001), have been widely used as the core of various spintronic devices such as magnetoresi…
Band-folding-driven high tunnel magnetoresistance ratios in (111)-oriented junctions with SrTiO barriers
Keisuke Masuda, Hiroyoshi Itoh, Yoshiaki Sonobe +3
We theoretically study the tunnel magnetoresistance (TMR) effect in (111)-oriented magnetic tunnel junctions (MTJs) with SrTiO barriers, Co/SrTiO/Co(111) and Ni/SrTiO$_…
Giant oscillatory tunnel magnetoresistance in CoFe/MgO/CoFe(001) junctions
Thomas Scheike, Zhenchao Wen, Hiroaki Sukegawa +1
The tunnel magnetoresistance (TMR) effect observed in magnetic tunnel junctions (MTJs) is commonly used in many spintronic applications because the effect can easily convert from l…
Enhanced Tunnel magnetoresistance in Fe/Mg4Al-Ox/Fe(001) Magnetic Tunnel Junctions
Thomas Scheike, Zhenchao Wen, Hiroaki Sukegawa +1
Spinel MgAl2O4 and family oxides are emerging barrier materials useful for magnetic tunnel junctions (MTJs). We report large tunnel magnetoresistance (TMR) ratios up to 429% at roo…
Strain Engineering of Magnetic Anisotropy in Epitaxial Films of Cobalt Ferrite
Hiroshige Onoda, Hiroaki Sukegawa, Jun-ichiro Inoue +1
Perpendicular magnetic anisotropy (PMA) energy up to MJ m is demonstrated in this study by inducing large lattice-distortion exceeding 3% at room…
