Abstract The pulsed laser deposition system equipped with in-situ reflection high-energy electron diffraction (RHEED) was used in this work. The LSMO films (13 u.c.) were deposited on three different substrates (SrTiO₃, (LaSr)(AlTa)O₃, LaAlO₃) with two crystalline orientations (001) and (110). The atomic force microscopy (AFM) was used to characterize the film surface morphology and roughness. The magnetic anisotropy was measured by the physical properties measurement system (PPMS). The orbital occupation of Mn ions in the LSMO film was proved by the X-ray absorption spectroscopy. In summary, no matter what substrates with orientations the LSMO films are deposited on, the electrons of Mn ions preferentially occupy the in-plane orbital and the LSMO films display the in-plane magnetic easy axis under tensile strain. In contrary, the electrons of Mn ions preferentially occupy the out-of-plane orbital and the LSMO films exhibit the out-of-plane magnetic anisotropy under compressive strain.

Key words： pulsed laser deposition system strain and orientation ultrathin LSMO films anisotropy orbital occupation
