MnAs1-xSbx (x = 0.068, 0.073) materials were fabricated by means of underwater shock compaction technique. A peak shock pressure of water acting on the powders was about 16 GPa. It was confirmed that underwater shock compaction leads to the compositional inhomogeneity, broad magnetic transition and lower magnetization and magnetic entropy changes of MnAs1-xSbx. However, these problems were improved by a post-annealing. Consequently, the post-annealed samples after the shock compaction exhibit the sharp magnetic transitions and high magnetic entropy changes of in a field of 1 T.
