摘 要：<正> The structure and intrinsic magnetic properties of RFeM（M=V or Ti）,type 1:12,have been studied bymagnetic measurement and X-ray diffraction.They are body-centered tetragonal ThMn12structure.Thechanges of crystal lattice constants coincide with that of their element radii.Curie temperature is decided mainlyby the exchange interactions of 3d-3d and 3d-4f atom pairs.The data obtained by mean-field approximationagree well with experimental values.The magnetic moment coupling in these compounds for LRE isferromagnetic,and for HRE is antiferromagnetic.At low temperature,anisotropy field is decided by REsublattice.In this paper,the influence of magnetic properties of cobalt and nickel replacing iron has also beenstudied.
