Abstract

Two CaMnBSbO6 (B = Cr and Fe) high-pressure double double perovskites are reported. Spins in CaMnCrSbO6 order below TC = 49 K into a collinear ferrimagnetic arrangement with spins in the xy plane. CaMnFeSbO6 has the same ordered magnetic structure below TC1 = 55 K, but also shows a second magnetic transition at TC2 = 21 K where the spins reorient towards the z axis. This may reflect a greater degree of magnetic disorder for B = Fe and A-B intersite charge transfer may also be significant.
