Abstract
The assumption that the ordered magnetic moments of randomly distribut ed heavy and light f atoms with positive in-plane exchange are antipar allel is tested with neutron diffraction on (U1-xTbx)Co2Ge2 solid solu tions, having ThCr2Si2-type crystal structure and AF-I(+-+-) magnetic structure at approximate to 10 K. The measured ordered magnetic moment s (aligned along the tetragonal axis) per (U,Tb) site imply ferrimagne tic (U,Tb) planes, with Tb moments of 9.0+/-0.3 mu(B) (close to Tb mom ent in TbCo2Ge2) antiparallel to U moments of 1.1+/-0.3 mu(B) (slightl y lower than U moment in UCo2Ge2).
