Magnetic and magneto-optical studies of silver doped manganite film

We measured the magnetic and magneto-optical properties of a La0.9Ag0.1MnO3 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.
