Description
Summary:The dependence between the coercive force and the average hysteresis loop record time was revealed in sintered [([Pr.sub.1-x]D[y.sub.x]).sub.13][([Fe.sub.1- y][Co.sub.y]).sub.79][B.sub.8] magnets. The coercive force was established to grow by 22% with an increase in the average hysteresis loop sweep rate within a range of 1.1 x [10.sup.2] - 3 x [10.sup.5] Oe/min, obeying a logarithmic dependence on the loop passage velocity with saturation at low rates. Some domain structure transformations produced by a magnetic field in the process of magnetization were established by magnetic force microscopy.
