摘要：

A phenomenological model of the formation of exchange bias field and coercivity of polycrystalline ferromagnet/antiferromagnet composites is constructed by an example of the Fe19Ni81/Fe50Mn50 system. Based on the experimental data on temperature variations of the hysteresis properties, the estimation of distributions of crystallite blocking temperature and crystallite magnetic anisotropy constant for the antiferromagnetic layer is performed. The obtained results are used in order to perform the micromagnetic simulation of the temperature dependences of the coercivity and exchange bias field of ferromagnetic layer. It is shown that the micromagnetic model can be used successfully for the analysis and prediction of hysteresis properties of film with the exchange bias.
