Observation of charge-to-spin conversion with giant efficiency at NiFe/BiWO interface
Saikat Das, Satoshi Sugimoto, Varun Kumar Kushwaha +2
Magnetization switching using spin-orbit torque offers a promising route to developing non-volatile memory technologies. The prerequisite, however, is the charge-to-spin current co…
Deterministic influence of substrate-induced oxygen vacancy diffusion on thin film growth
Saikat Das, Tadakatsu Ohkubo, Shinya Kasai +1
In oxide epitaxy, the growth temperature and background oxygen partial pressure are considered as the most critical factors that control the phase stability of an oxide thin film.…
Voltage-controlled magnetic anisotropy under the electronic structure modulation in quantum wells
Qingyi Xiang, Yoshio Miura, Muftah Al-Mahdawi +8
Voltage-controlled magnetic anisotropy (VCMA) offers an emerging approach to realize energy-efficient magnetization switching in spintronic devices such as magnetic random access m…
Nonlinear electric field effect on perpendicular magnetic anisotropy in Fe/MgO interfaces
Qingyi Xiang, Zhenchao Wen, Hiroaki Sukegawa +5
The electric field effect on magnetic anisotropy was studied in an ultrathin Fe(001) monocrystalline layer sandwiched between Cr buffer and MgO tunnel barrier layers, mainly throug…
Giant interfacial perpendicular magnetic anisotropy in Fe/CuInGaSe beyond Fe/MgO
Keisuke Masuda, Shinya Kasai, Yoshio Miura +1
We study interfacial magnetocrystalline anisotropies in various Fe/semiconductor heterostructures by means of first-principles calculations. We find that many of those systems show…
Tunnel magnetoresistance and spin-transfer-torque switching in polycrystalline Co2FeAl full-Heusler alloy magnetic tunnel junctions on Si/SiO2 amorphous substrates
Zhenchao Wen, Hiroaki Sukegawa, Shinya Kasai +2
We studied polycrystalline B2-type Co2FeAl (CFA) full-Heusler alloy based magnetic tunnel junctions (MTJs) fabricated on a Si/SiO2 amorphous substrate. Polycrystalline CFA films wi…
