Effect of Cu and Zn Substitutions on MnSb Properties

The NiAs‐type solid solutions based on manganese antimonide Mn1.1Sb with Zn or Cu (up to 10 at % of substituting component) have been studied by 57Fe Mossbauer spectroscopy. It has been shown that the replacement of the manganese antimonide by Cu or Zn does not appreciably affect the main Mossbauer parameters in comparison to those of the parent compound. Two different values of hyperfine magnetic field at Fe are present in all the samples and can be attributed to the metal atoms located in MeI and MeII positions. The substitution of Cu or Zn for manganese antimonide leads to the redistribution of the metal atoms between two cation sublattices.
