Abstract
The magnetic properties of an anisotropic, epoxy resin bonded magnet made from Magnequench powder of MQA-T type were investigated. The magnetization reversal processes and the magnetic parameters were examined by measurement of virgin magnetization curve, the major and sets of minor hysteresis loops. The coercivity as a function of maximum magnetizing field were determined. The field dependence of the reversible and irreversible magnetization components during the magnetization and demagnetization processes was investigated by measuring sets of recoil curves. As it results from the initial magnetization curve shape and the field dependence of coercivity the magnetization reversal mechanism appeared to be the pinning one.
