抄録

Crystal structures and magnetic properties of Ir-Mn-Sb alloys were studied through X-ray and magnetic analyses. It has been found that the intermetallic compounds of the Clb-type structure exsist in the IrMn1+xSb system and forms a solid solution in the composition range of x=0.5∼0.8. IrMn1.5Sb and IrMn1.8Sb alloys of the Clb-type have lattice parameters of about 6.154 and 6.141 Å at room temperature, magnetic moments nB of 2.6 and 2.1 μB per Mn atom at absolute zero, and Curie temperatures Tc of 278 and 258 K, respectively. From the temperature dependence of reciprocal magnetic susceptibility 1⁄χg, these Clb-type alloys are expected to change from the ferromagnetism to the ferrimagnetism with increasing Mn content.
