摘要: We report on the magneto-optical measurements of an epitaxial SrRuO3 film grown SrTiO3 (0 0 1), which previously was determined to be single domain orientated by x-ray diffraction and Raman spectroscopy techniques. Our experiments reveal a large Kerr rotation, reaches maximum value about 0.5° at low temperature. By measuring magnetic hysteresis loops different temperatures, we temperature dependence rotation in polar configuration. Values anisotropic magnetoresistance ∼20% have been measured. These values are remarkably higher than those other metallic oxides such as manganites. This striking difference can attributed strong spin-orbit interaction Ru 4d ion compound.
