title = "Magnetic and electronic properties of B -site-ordered double-perovskite oxide L a2CrMn O6 thin films",
abstract = "We report on magnetic and electronic properties of the B-site-ordered double-perovskite La2CrMnO6 films grown by pulsed-laser deposition. The magnetic-field dependence of magnetization curves showed hysteresis at low temperatures regardless of the degree of Cr/Mn order and the saturation magnetization became smaller for the higher-Cr/Mn-ordered film. The x-ray absorption spectroscopy and x-ray magnetic circular dichroism measurements suggested antiferromagnetic coupling between Cr3+ and Mn3+ ions, resulting in ferrimagnetism of the B-site-ordered double-perovskite La2CrMnO6. A band structure was established by combining these results together with the synchrotron-radiation photoemission and optical spectra. We discuss the magnetic states among the B-site-ordered La2B′MnO6 (B′:3d transition-metal elements from V to Ni) being basically consistent with the Kanamori-Goodenough rule.",
