Abstract
Long-term investigations of the time decay of the reversible magnetic permeability of two soft ferromagnetic amorphous alloys have been performed at room temperature over the extended time interval 10−4–106s. The involved processes of directional ordering are characterized by a wide distribution of activation energies. The activation energy spectrum has been analysed using the canonical Primak procedure.
A suitable experimental method, allowing one to interface directly with the kinetics of the atomic ordering events, is proposed for investigating the validity of the current model of independent ordering processes.
