DOI: 10.1016/j.jmmm.2019.165968
Abstract: Abstract The orthorhombic pseudo-perovskite series NdMn1-xFexO3+δ has negative magnetization, i.e. magnetization directed opposite to an applied field under certain conditions, for x = 0.2 and x = 0.25. We have investigated the microscopic origin of this phenomenon for x = 0.2… read more here.

DOI: 10.1021/acs.chemmater.9b02637
Abstract: We present derivatives of the Al3Ti-type of structure Al8FeMo3 (Al9–xFexMo3) and Al8CuMo3. Structural features are a molybdenum-square lattice and a solid solution of iron (copper) on aluminum sites. By substitution of Al with 3d-transition metals… read more here.
