Description

LaCoO3 (LCO) thin films do show a strain induced ferromagnetic phase transition below 85K. In order to elucidate the coupling between strain and magnetization, we have grown epitaxial LCO thin films on (001),(111) and (110) oriented (LaAlO3)0.3(Sr2AlTaO6)0.7 single crystal substrate with different film thickness. The films were grown by pulsed laser depositions and are differently strained because of the grown direction. The magnetization reversal loops were recorded by light modulated magneto-optical Kerr effect (MOKE) magnetometry whereas strain characterization was carried out by reciprocal space mapping on a four-circle X-ray diffractometer. The magnetic anisotropy as a function of strain is studied. Preliminary results are presented
