Mössbauer and magnetic studies of amorphous and nanocrystalline Fe85.4Zr6.8−xNbxB6.8Cu1 (x=0,1,2) alloys

Abstract It was stated that the addition of Nb to the Fe 85.4 Zr 6.8 B 6.8 Cu 1 alloy leads to the decrease of the average hyperfine field at 57 Fe nuclei and Curie temperature of the amorphous materials. Moreover, the amount of the α-Fe phase in the nanocrystalline samples increases with the niobium content. The nanocrystalline alloy containing 2 at% Nb exhibits the highest initial magnetic susceptibility.
