摘要：

Manganese aluminate spinels and Hausmannites, namely (MnxAl1-x)(3)O-4, with compositions varying between x = 0.33 and x = 1.00 have been synthesized by sintering of MnO and Al2O3 mixtures. Lattice parameters of these spinels and Hausmannites Increase linearly with increasing Mn content and depend on neither sintering temperature nor cooling rate, Magnetic hysteresis loops at 5 K show non-saturating features up to 5 T. Ferrimagnetic Curie temperatures of spinels and Hausmannites both increase monotonically with increasing Mn content.
