Spontaneous atomic ordering and magnetism in epitaxially stabilized double perovskites
Abstract
We have studied the atomic ordering of B-site transition metals and magnetic properties in the pulsed laser deposited films of La<sub>2</sub>CrFeO<sub>6</sub> (LCFO) and La<sub>2</sub>VMnO<sub>6</sub> (LVMO), whose bulk materials are known to be single perovskites with random distribution of the B-site cations. Despite similar ionic characters of constituent transition metals in each compound, the maximum B-site order attained was surprisingly high, ∼90% for LCFO and ∼80% for LVMO, suggesting a significant role of epitaxial stabilization in the spontaneous ordering process. Magnetization and valence state characterizations revealed that the magnetic ground state of both compounds was coincidently ferrimagnetic with saturation magnetization of ∼2 μB per formula unit, unlike those predicted theoretically. In addition, they were found to be insulating with optical band gaps of 1.6 and 0.9 eV for LCFO and LVMO, respectively. Our results present a wide opportunity to explore novel magnetic properties of binary transition metal perovskites upon epitaxial stabilization of the ordered phase.
