摘要：

In this paper the sweep rate (R = dH/dt) dependence of coercivity is calculated, from these calculations the sweep rate dependence of H(c)(R) can be expressed as a power series of ln(R) and the coefficients of the expansion give a useful method of determining the mean anisotropy field of the system.
