  • Abstract
    The temperature dependence of the coercive field (Hc ) and the thermal fluctuation field (Hf) of Nd-Fe-B sintered magnets was measured from 100 K to 500 K. It was found that a linear relationship exists between lgH f and lgHc in this temperature range. The relationship between lg Hc and lgHf was deduced from Gaunt´s localized weak pinning model. Values of l gHc calculated from the derived relationship are in very good agreement with experimental values
