Magnetic behaviour of Sm6Mn23−xFex compounds

Results of magnetic investigations on Sm6Mn23-xFex compounds performed over a wide temperature range are presented. It was found that replacing the Mn atoms in Sm6Mn23 and Fe atoms in Sm6Fe23 by Fe and Mn, respectively, causes a rapid reduction in both the Curie temperature and the magnetic moment. No magnetic order was found in the 4 < x < 8 range. The temperature dependence of the reciprocal susceptibility of the investigated compounds can be described using the Néel law.
