CRYSTALLIZATION , *MAGNETIC properties - Abstract
The structure evolution and low-field magnetic properties (i.e. the magnetic susceptibility and its disaccommodation) during transformation of the Fe85.4Zr6.8−xNbxB6.8Cu1
(x=0,1) alloys from the amorphous to the nanocrystalline state are investigated. It was stated that at early stages of crystallization, the iron content in the amorphous matrix does not change. However, the interfacial layer is poorer in iron in comparison with the amorphous matrix. The annealing of the amorphous samples below the crystallization temperature leads to the decrease of the hyperfine field due to the invar effect. Moreover, at early stages of crystallization, the samples exhibit “magnetic hardening”. The magnetic susceptibility disaccommodation of the investigated alloys is mainly connected with relaxation processes occurring in the amorphous phase. [Copyright &y& Elsevier]- Published
