Abstract

Nanocrystalline Fe90Zr7B2Cu1 with ferromagnetic BCC nanocrystals of about 10-20 nm size embedded in a residual amorphous matrix was produced from amorphous precursor by partial crystallization. A significant increase in the Curie temperature of the residual amorphous phase (T-C) as compared to that of the amorphous precursor was found by combined bulk magnetic and Mossbauer measurements. The unusual increase of T-C for alloys with different nanocrystalline fractions correlates with the quantity of the BCC phase.
