Effects of voids in MR layer and SAL on MR response of a SAL biased MR head

概要

論文の詳細を見る
A micromagnetic simulation of a SAL biased MR head was done and effects of voids in MR layer and SAL on MR response have been described. Volume of voids was varied from 0 to 10.5%. It was found that the MR response becomes lower value, if volume percent of voids or nonmagnetic elements in the MR layer and SAL becomes larger. When the volume fraction of voids was high MR response showed wiggles in a certain range of applied field. In the case of no void, effects of M_s of SAL, shunt current and M_s of permanent magnets on MR response have been also studied.
