Spin-transfer Antiferromagnetic Resonance
Øyvind Johansen, Hans Skarsvåg, Arne Brataas
Currents can induce spin excitations in antiferromagnets, even when they are insulating. We investigate how spin transfer can cause antiferromagnetic resonance in bilayers and tril…

Spin Pumping and Inverse Spin Hall Voltages from Dynamical Antiferromagnets
Øyvind Johansen, Arne Brataas
Dynamical antiferromagnets pump spins efficiently into adjacent conductors as ferromagnets. The high antiferromagnetic resonance frequencies represent a challenge for experimental…

Current driven spin-orbit torque oscillator: ferromagnetic and antiferromagnetic coupling
Øyvind Johansen, Jacob Linder
We consider theoretically the impact of Rashba spin-orbit coupling on spin torque oscillators (STOs) in synthetic ferromagnets and antiferromagnets that have either a bulk multilay…
