Automatic hysteresis loop measurements during heavy-ion irradiation of ferromagnetic metallic glasses

To investigate the mechanisms involved in ferromagnetic metallic glasses, the authors have performed heavy-ion irradiation, during which the changes in magnetic properties have been studied in situ as a function of ion dose. The object of this paper is to describe the experimental set-up to record in situ B(H) loops and initial permeability μ_i of Metglas 2705 MN toroids
