| Microstructure and thermomagnetic properties of the as-quenched Gd75Ge15Si5Pr5 (wt.%) alloy are studied. Multiphase composition of the investigated sample was confirmed by microstructural as well as magnetic investigations. The presence of the Gd68Ge18Si7Pr7 and Gd76Ge14Si5Pr5 regions with different atom concentration was confirmed by SEM/EDS analysis and temperature dependence of magnetic mass susceptibility. From DC magnetic measurements of magnetization versus temperature performed in zero-field/field cooled modes, and magnetic mass susceptibility investigations the Curie temperature (283 K and 278 K, respectively) and magnetic behavior were studied. Moreover, the structural investigations were performed as temperature dependence of specific heat capacity. |
