Effect of interaction on the magnetization of single-domain particles

摘要: A model is proposed to permit the calculation of remanence in a magnetic tape that subject various magnetizing processes. combination regenerative local field and Preisach diagram account for particle interaction. It shown that, although not stable, its shape does have change as it moves, due changes bulk magnetization I. In fact, density function J(H+, H-) could be replaced by J(H+ + αI, H- -αI). The action necessary reduce calculated spread distribution, which many times observed value. best agreement between experiments obtained assuming fundamental spherical, consistent with "chain spheres" interaction-free magnetization.
