Magnetic coupling between the different phases in nanocrystalline Fe-Si-B studied by small angle neutron scattering
- 1. Hahn-Meitner-Institut Berlin GmbH (Germany)
Description
The magnetic coupling in the two-phase nanostructure of Fe73.5Si15.5B7Nb3Cu1 has been investigated by SANS technique. The scattering function for partially aligned magnetic moments of ferromagnetic single domain particles following the Langevin statistics of superparamagnetism has been derived which describes the field and temperature dependency of the SANS profiles. Above the Curie temperature of the amorphous phase Tcam the nanocrystals show superparamagnetic scattering behaviour whereas below Tcam they interact by magnetostatic forces only and not by exchange coupling via the amorphous matrix.
