NUMERICAL-ANALYSIS OF THE MAGNETIZATION IN SOFT ADJACENT LAYER BIASEDMAGNETORESISTIVE SENSORS

A modified Dufort-Frankel method with relaxation is developed and appl ied to the static magnetization analysis of a magnetoresistive sensor, which is composed of a magnetoresistive layer magnetically fixed by a domain controlled antiferromagnetic layer, a nonmagnetic conducting l ayer, and a soft magnetic adjacent layer. This method is thought to be suitable for three-dimensional large-scale magnetic-multilayered syst ems. It clarifies the biased magnetization state of the magnetoresisti ve layer and soft adjacent layer with intermagnetostatic interaction.
