Abstract

Compounds of the compositions Fe_73.5Cu₁Nb ₃Si_13.5B₉ and Fe_73.5Cu₁Nb₃Si_16.5B₆ were studied in the as-cast state and after heat treatments. In the latter case the materials have a nanocrystalline structure. The stress dependence of the hysteresis loop and the magnetostriction was measured for the samples. In addition, the domain structure was studied. In the heat-treated material, a change in the sign of the magnetostriction constant was found with change in the external field
