| Summary:
To achieve efficient anti-damping switching of nanoscale magnetic memories
with perpendicular magnetic anisotropy using spin-orbit torque requires that
the anti-damping spin-orbit torque have a strong out-of-plane component. The
spin anomalous Hall effect and the planar Hall effect spin current produced by
a ferromagnetic layer are candidate mechanisms for producing such an
out-of-plane anti-damping torque, but both require that the magnetic moment of
the spin source layer be canted partly out of the sample plane at zero applied
magnetic field. Here we demonstrate such a canted configuration for a
ferromagnetic SrRuO3 layer and we characterize all vector components of the
torque that it produces, including non-zero out-of-plane anti-damping torques.
We verify that the out-of-plane spin component can be tuned by the orientation
of magnetic moment, with significant contributions from both the spin anomalous
Hall effect and the planar Hall effect spin current.
