Abstract

MnAs1-xSbx material is one of the ferromagnets which can contribute to a magnetic refrigeration system that is useable at room temperature. The consolidation experiments of MnAs1-xSbx (x=0.068, 0.073) powder are carried out by a shock compaction method using underwater shock wave with shock pressure of 16GPa. The magnetic entropy change, ΔSmag, of annealed sample (x=0.073) after press caused by a magnetic field of 1T is 27.8J/Kkg at the maximum value, and the sample annealed after press undergoes a first-order ferromagnetic to paramagnetic transition at 304.05K.
