Description

Nanocrystalline disordered Fe-Ge alloys are studied by X-ray analysis, Moessbauer spectroscopy and magnetic measurements. The alloys obtained have a BCC structure at x<32 and a B82 hexagonal one at x>32 at% Ge. The dependences of the average magnetic moment per Fe atom, hyperfine magnetic field at 57Fe nucleus and isomer shift on Ge concentration are obtained. The peculiarities of the concentration behaviour of magnetic properties are explained in terms of the local atomic and magnetic parameters of the Fe atom depending on the Ge nearest neighbours number
