Cu alloys (

Magnetic properties were mainly studied by the evolution of initial permeability from room temperature to 740°C. All the 500°C-annealed samples gave rise to an ultrafine structure composed of a residual amorphous matrix and

was systematically analyzed in terms of the effective anisotropy model. |
