ABSTRACT:
Process for the heat treatment, in a magnetic field, of a magnetic component made of a low-anisotropy soft magnetic material such as, for example, a 15/80/5 FeNiMo alloy, an amorphous Co-based alloy or a nanocrystalline FeSiCuNbB alloy, in which the magnetic component is annealed at a temperature below the Curie point of the magnetic material and, during the annealing, the magnetic component is subjected to a DC or AC, unidirectional, longitudinal or transverse magnetic field, in which process the magnetic field is applied in the form of a succession of pulses each comprising a first part during which the intensity of the magnetic field reaches a maximum value and a second part during which the intensity of the magnetic field has a minimum value.
