摘要：

Normally, theories of magnetic noise after ac erasing take into account residual correlations among magnetic particles either through an ad hoc assumption or by numerical simulation of the erasing process [IEEE Trans. Magn. MAG-23, 1767 (1987); IEEE Trans. on Magn. MAG-20, 412 (1984); IEEE Trans. Magn. MAG-19, 899 (1983).] In this paper we present a theory for a particulate medium based on a pseudo-equilibrium calculation of the correlation, with the ac field acting as the heat bath. The results are compared with experiment.
