Abstract

The exchange coupling and the microstructures of the Ta/(Ni-Fe, Co-Fe)/Mn-Ir-Pt/Ta multilayers have been investigated by varying the compositions of Mn-Ir-Pt film. For exchange-bias layer (EBL) comprising NiFe/CoFe/Mn_79.7Ir_18.4Pt_1.9 structures, the exchange bias field (H_ex) of 441 Oe (exchange energy Jex of 0.236 erg/cm²) and the blocking temperature (T_b) of 260°C was obtained. In addition, it is found that the Mn-Ir-Pt EBL's have the polycrystalline structure and (111) texture. The crystallographic structure of the Mn-Ir-Pt film was face centered cubic (FCC).
