Abstract :
Compounds of the compositions Fe73.5Cu1Nb 3Si13.5B9 and Fe73.5Cu1 Nb3Si16.5B6 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
