Languages of publication
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.
