Abstract
Crystal structures and magnetic properties of Rh–Mn–Sb alloys have been investigated by means of X-ray and magnetic analysis. It is shown that Clb type alloys exsist near the stoichiometric composition in the Rh–Mn–Sb system. Rh0.90 Mn1.20 Sb0.90 and Rh1.10 Mn1.10 Sb0.80 alloys with the crystal structure of the Clb type have lattice parameters of about 6.145 and 6.170 Å at room temperature, saturation magnetizations of 79.5 and 75.0 emu/g at absolute zero, saturation magnetic moments of 3.19 and 3.29 μB per Mn atom at absolute zero, and Curie temperatures of 325 and 350°K, respectively. Moreover, the reciprocal magnetic susceptibility of these alloys has been found to satisfy the Curie-Weiss law above the Curie temperature.
