Title: High-Pressure Synthesis of Lu 2NiIrO 6 with Ferrimagnetism and Large Coercivity

Abstract

Double perovskite Lu 2NiIrO 6 was synthesized at high pressure (6 GPa) and high temperature (1300 °C). Synchrotron powder x-ray diffraction indicates that its structure is a monoclinic double perovskite (space group P2 1/n) with a small, 9 % Ni/Ir anti-site disorder. X-ray absorption near edge spectroscopy measurements established Ni 2+ and Ir 4+ formal oxidation states. Magnetic studies indicate a ferrimagnetic transition, TC at 210 K. The low-temperature magnetization curve of Lu 2NiIrO 6 features broad hysteresis with a coercive field as high as 48 kOe. These results are encouraging to search for hard magnets in the class of 3d-5d double perovskite oxides.
