Spin orbit effects in CoFeB/MgO hetereostructures with heavy metal underlayers
Jacob Torrejon, Junyeon Kim, Jaivardhan Sinha +1
We study effects originating from the strong spin orbit coupling in CoFeB/MgO heterostructures with heavy metal (HM) underlayers. The perpendicular magnetic anisotropy at the CoFeB…
Spin-orbit torque in Cr/CoFeAl/MgO and Ru/CoFeAl/MgO epitaxial magnetic heterostructures
Zhenchao Wen, Junyeon Kim, Hiroaki Sukegawa +2
We study the spin-orbit torque (SOT) effective fields in Cr/CoFeAl/MgO and Ru/CoFeAl/MgO magnetic heterostructures using the adiabatic harmonic Hall measurement. High-quality perpe…
Spin Hall magnetoresistance in metallic bilayers
Junyeon Kim, Peng Sheng, Saburo Takahashi +2
Spin Hall magnetoresistance (SMR) is studied in metallic bilayers that consist of heavy metal (HM) layer and a ferromagnetic metal (FM) layer. We find nearly a ten-fold increase of…
Anomalous temperature dependence of current induced torques in CoFeB|MgO heterostructures with Ta based underlayers
Junyeon Kim, Jaivardhan Sinha, Seiji Mitani +5
We have studied the underlayer thickness and temperature dependences of the current induced effective field in CoFeB|MgO heterostructures with Ta based underlayers. The underlayer…
Interface control of the magnetic chirality in CoFeB|MgO heterosctructures with heavy metal underlayers
Jacob Torrejon, Junyeon Kim, Jaivardhan Sinha +4
Recent advances in the understanding of spin orbital effects in ultrathin magnetic heterostructures have opened new paradigms to control magnetic moments electrically. The Dzyalosh…
Quantitative characterization of the spin orbit torque using harmonic Hall voltage measurements
Masamitsu Hayashi, Junyeon Kim, Michihiko Yamanouchi +1
Solid understanding of current induced torques is key to the development of current and voltage controlled magnetization dynamics in ultrathin magnetic heterostructures. To evaluat…
