Abstract

The structure, magnetic properties and magnetostriction of are-melted polycrystalline Sm0.9Pr0.1(Fe1-xMnx)(2) (0 less than or equal to x less than orequal to 0.2) alloys were investigated by microscopy, X-ray diffraction, A. C. initial susceptibility, vibrating sample magnetometer and standard strain gauge techniques. It was found that the matrix consists almost entirely of the MgCu2-type cubic Laves phase. The lattice parameter increases, whilethe Curie temperatures decrease with increasing x. The spontaneous magnetostriction lambda(111,) polycrystalline saturation magnetostriction lambda(s) and saturation magnetization M-s decrease slowly for x less than or equalto 1.0 and abruptly for x > 1.0 with increasing Mn content. The changes inthe magnetization and magnetostriction can be understood on the basis of the decrease of the 3d-sublattice moment.(1) (C) 2000 Elsevier Science S.A. All rights reserved.
