abstract = {Manganites have shown potential in spintronics because they
exhibit high spin polarization. Here, by ferromagnetic
resonance we have studied the damping properties of
La0.67Sr0.33MnO3/Pt bilayers which are prepared by oxide
molecular beam epitaxy. The damping coefficient (α) of a
La0.67Sr0.33MnO3 (LSMO) single layer is found to be 0.0104.
However the LSMO/Pt bilayers exhibit a decrease in α with
an increase in Pt thickness. This decrease in the value of
α is probably due to high anti-damping like torque.
Furthermore, we have investigated the angle dependent
inverse spin Hall effect (ISHE) to quantify the spin pumping
voltage from other spin rectification effects such as the
anomalous Hall effect and anisotropic magnetoresistance. We
have observed a high spin pumping voltage (∼20 μV). The
results indicate that both anti-damping and spin pumping
phenomena occur simultaneously.},
