Dynamic ferromagnetic proximity effect in photoexcited semiconductors
Gerrit E. W. Bauer, Arne Brataas, Yaroslav Tserkovnyak +3
The spin dynamics of photoexcited carriers in semiconductors in contact with a ferromagnet is treated theoretically and compared with time-dependent Faraday rotation experiments. T…
Non-monotonic angular magnetoresistance in asymmetric spin valves
Jan Manschot, Arne Brataas, Gerrit E. W. Bauer
The electric resistance of ferromagnet/normal-metal/ferromagnet perpendicular spin valves depends on the relative angle between the magnetization directions. In contrast to common…
The spin-torque transistor
Gerrit E. W. Bauer, Arne Brataas, Yaroslav Tserkovnyak +1
A magnetoelectronic thin-film transistor is proposed that can display negative differential resistance and gain. The working principle is the modulation of the soure-drain current…
Dynamic exchange coupling and Gilbert damping in magnetic multilayers
Yaroslav Tserkovnyak, Arne Brataas, Gerrit E. W. Bauer
We theoretically study dynamic properties of thin ferromagnetic films in contact with normal metals. Moving magnetizations cause a flow of spins into adjacent conductors, which rel…
Magnetovibrational coupling in small cantilevers
Alexey A. Kovalev, Gerrit E. W. Bauer, Arne Brataas
A nano-magnetomechanical system consisting of a cantilever and a thin magnetic film is predicted to display magnetovibrational modes, which should enable applications for sensors a…
