Study of B8 - type solid solutions of Al and Si in manganese antimonide

The Mn1.1Sb1.yAly (0 less-than or equal to y less-than or equal to 0.2) and Mn1.1Sb1-ySiy (0 less-than or equal to y less-than or equal to 0.1) solid solutions with the B8-type of crystal structure were obtained. The magnetic measurement revealed that the partial substitution of Sb atoms by Al or Si practically do not affect the specific magnetization and Curie temperatures. Mossbauer data showed the local redistribution of atoms in solid solutions by comparison with that in the parent Mn1.10Sb.
