Abstract
The characterization and magnetic properties of YFe12âxMox (x=2.0, 2.5 and 3.0) with the ThMn12-type structure, and the magnetocaloric effect of YFe9.5Mo2.5 were investigated. A directional growth was observed in YFe10Mo2 alloy. A broad peak in the zero-field-cooling (ZFC) magnetization curve of the YFe12âxMox compounds is ascribed to the existence of ferromagnetic clusters with different site moments and scattered orientations of the moments. The broad range of the peak is reduced with increasing Mo content. A weak peak is observed near 190 K in the ZFC curve of YFe9Mo3, which is associated with the 8i sites being mostly occupied by Mo atoms. YFe9.5Mo2.5 has a magnetic entropy change of â1.09 J/kg K for a field change of 5 T at 277 K.
