Abstract

The magnetic anisotropy of epitaxial La0.67Sr0.33MnO3 LSMO thin films on vicinal, TiO2-terminated SrTiO3 substrates is investigated. Atomic force microscopy shows a regular step-terrace structure on the LSMO surface which is a replication of the surface of the substrate. The films show in-plane uniaxial magnetic anisotropy at room temperature, with the easy axis along the step direction. At low temperature the films show biaxial crystalline anisotropy with easy axes along 110, and hard axes along the 100 direction of LSMO.
