Abstract

We measured the magnetic and magneto-optical properties of a La_0.9Ag_0.1MnO₃ thin film with thickness of 320 nm and effective Curie temperature T_C = 317 K. We have observed that the easy magnetization axis (EMA) is oriented in-plane to the film surface and stripe domain structures with walls oriented along the EMA. The Brillouin light-scattering spectrum shows that dispersion for the acoustic phonons is highly dependent on the external magnetic field.
