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 (TC) as compared to that of the amorphous precursor was found by combined bulk magnetic and Mössbauer measurements. The unusual increase of TC for alloys with different nanocrystalline fractions correlates with the quantity of the BCC phase.
