Crystal and magnetic structures of high pressure Mn2ScBO6 double perovskites
Transition metal oxides continue to be of great important for magnetism and other properties, and double perovskite (DPv) cation ordering is frequently used to induce and tune physical properties. We propose here to study two Mn2ScBO6-based DPv materials recently discovered at high pressure. 1. A new series of DPv Mn2-xCoxScSbO6 solid solutions x = 0.5, 1, 1.5 where small Co2+ at A-sites in (double) perovskites is very unusual. They have two magnetic transitions, at 51 K and 14 K for x = 1, and likely canted antiferromagnetic Mn/Co spin order. 2. The new DPv Mn2ScRuO6 which has a broad magnetic transition at 105 K and a weak possible second transition at 24 K. Hysteresis measurements shows ferrimagnetism with a saturated moment of 1.02 BM/f.u., in contrast to antiferromagnetism reported in A2ScRuO6 (A = Ba, Sr) DPv's synthesized at ambient pressure. D20 is needed to determine the crystal structures in high resolution mode (wavelength = 1.54 Å), given small monoclinic distortions, as well as magnetic structures and their thermal evolution in high flux mode (wavelength = 2.41 Å).
