Abstract
- The magnetocrystalline anisotropy of La0.67Ba0.33MnO3 (LBMO) epitaxial films suffering large compressive strain on LaAlO3 (LAO) substrates (LBMO/LAO) was investigated by ferromagnetic resonance (FMR) in the temperature range between 2 and 320 K. By mapping out the dependence of the FMR position on the angle between the applied magnetic field and crystallographic axes of the films, a large easy-plane anisotropy has been found in such compressive strained LBMO films, which is in contrast to the general tendency presented in strained manganite films. Furthermore, the excellent epitaxial crystallographic orientation due to the LAO substrates gives rise to an appreciable fourfold symmetry of the in-plane anisotropy with easy-axis along the [110] direction. The results are discussed by taking tolerance factor and giant magnetostriction of Ba-doped manganites into account. [ABSTRACT FROM AUTHOR]
