摘要:
Mn1.2Fe0.8P0.76Ge0.24 room temperature magneto-caloric compounds were prepared by mechanical alloying and subsequent spark plasma sintering (SPS) technique. XRD and SEM were used to analyze the phase composition and the microstructure of the sintered bulk samples. Results show that the sintered bulk samples have homogeneous and compact microstructure, but with a little MnO and Fe3Mn4Ge6. DSC curve of the sintered bulk Mn1.2Fe0.8P0.76Ge0.24 compound shows that the Curie temperature T-C of the sample is around -10 degrees C, and at -7 degrees C the magnetic entropy change is 23 J/(kg.K)
