Effect of carbonation on the structure and magnetic properties of YFe11−xCoxTiCy alloys

YFe11-xCoxTi compounds (x=,0.5, 1, 1.5 and 2) with ThMn12-type structure have been synthesized by induction melting for x=0, 1 and 2. The carbides YFe11-xCoxTiC were obtained by solid-solid reaction. X-ray diffraction method was used in order to analyze the influence of Co substitution and carbonati...

Summary:YFe11-xCoxTi compounds (x=,0.5, 1, 1.5 and 2) with ThMn12-type structure have been synthesized by induction melting for x=0, 1 and 2. The carbides YFe11-xCoxTiC were obtained by solid-solid reaction. X-ray diffraction method was used in order to analyze the influence of Co substitution and carbonation on the cell parameters and interatomic distances of 3d sublattice. The influence of Co substitution and carbonation on the Curie temperature TC and saturation magnetization MS are interpreted in a rigid band model, by the effect of the 3d band filling on the exchange interaction between 3d (Fe and Co) atoms.
