Current-induced spin torque resonance of a magnetic insulator
Michael Schreier, Takahiro Chiba, Arthur Niedermayr +7
Pure spin currents transport angular momentum without an associated charge flow. This unique property makes them attractive for spintronics applications, such as torque induced mag…
Current-induced spin torque resonance of magnetic insulators affected by field-like spin-orbit torques and out-of-plane magnetizations
Takahiro Chiba, Michael Schreier, Gerrit E. W. Bauer +1
The spin-torque ferromagnetic resonance (ST-FMR) in a bilayer system consisting of a magnetic insulator such as Y3Fe5O12 and a normal metal with spin-orbit interaction such as Pt i…
Current-induced spin torque resonance of magnetic insulators
Takahiro Chiba, Gerrit E. W. Bauer, Saburo Takahashi
We formulate a theory of the AC spin Hall magnetoresistance (SMR) in a bilayer system consisting of a magnetic insulator such as yttrium iron garnet (YIG) and a heavy metal such as…
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…
