| 4 | An Anomalous Kerr Loop of LaBaMnO Thin Film显示文摘An anomalous Kerr loop was observed in an oriented LaBaMno film annealed in oxygen. Many tiny crystal columns were observed with scanning tunneling microscope and magnetic force microscope. The magnetic moment m in the column is perpendicular outward to the surface, which forms a surface phase with spin pinning state. This spin pinning results in the obvious asymmetrical Kerr loop of magneto-optical effect when the magnetic field is in the two opposite directions vertical to the surface. | Hou, BH Xu, QL Ji, SZ Zhang, TP Peng, P Shang, CH Wang, YJ Xu, L Zhang, Y | 1998 | Journal of Materials Science & Technology1998，14，4： | 0 |
