Macrospin Tunneling and Magnetopolaritons with Nanomechanical Interference
Alexey A. Kovalev, Lorien X. Hayden, Gerrit E. W. Bauer +1
We theoretically address the quantum dynamics of a nanomechanical resonator coupled to the macrospin of a magnetic nanoparticle by both instanton and perturbative approaches. We de…
Feedback control of noise in spin valves by the spin-transfer torque
Swarnali Bandopadhyay, Arne Brataas, Gerrit E. W. Bauer
The miniaturisation of magnetic read heads and random access memory elements makes them vulnerable to thermal fluctuations. We demonstrate how current-induced spin-transfer torques…
Spin Seebeck insulator
K. Uchida, J. Xiao, H. Adachi +10
Thermoelectric generation is an essential function of future energy-saving technologies. However, this generation has been an exclusive feature of electric conductors, a situation…
