Abstract

The giant magneto-impedance (GMI) effect for Fe_73.5Cu₁Nb₃Si_13.5B₉ nanocrystalline ribbons is investigated in the temperature range between room temperature and 873 K. The thermal dependence of GMI effect reveals the enhancement of Curie temperature of the amorphous matrix, reflecting the exchange coupling between the α-FeSi grains as well as the compositional changes of the amorphous matrix itself. However, the dipolar interaction between grains is suggested to be responsible for the non-zero GMI effect after the magnetic phase transition of the amorphous matrix.
