Description
The evolution of magnetic properties and local atomic ordering during thermal annealing has been studied for amorphous Fe75Ni5B15Si5 thin films. Resistivity, vibrating sample magnetometer (VSM), ferromagnetic resonance (FMR), extended x-ray absorption fine structure (EXAFS), and Moessbauer effect (ME) measurements were taken on samples annealed at various temperatures ranging to film crystallization. The as-deposited samples are in a close-packed structure with little short-range order. Samples annealed above 200 degree C show ordering of the boron shell, but no indication of long-range ordering. With the exception of the anisotropy and coercive fields, no change in the magnetic or microwave magnetic parameters is observed for these samples prior to crystallization. Samples annealed above 400 degree C show indications of crystallization for all measurements
