Abstract:Charge-spin
interconversion processes underpin the generation of
spin–orbit torques in magnetic/nonmagnetic bilayers. However,
efficient sources of spin currents such as 5d metals
are also efficient spin sinks, resulting in a large increase of magnetic
damping. Here we show that a partially oxidized 3d metal can generate a strong orbital torque without a significant
increase in damping. Measurements of the torque efficiency ξ
and Gilbert damping α in CoFe/CuO
x
and CoFe/Pt indicate that ξ is comparable in the… Show more
