Abstract
The exchange coupling and the microstructures of the Tal(Ni-Fe, Co-Fe)/Mn-I
r-Pt/Ta multilayers have been investigated by varying the compositions of M
n-Ir-Pt film. For exchange-bias layer (EBL) comprising NiFe/CoFe/Mn79.7Ir18
.4Pt1.9 structures, the exchange bias field (H-ex) of 441 Oe (exchange ener
gy Jex of 0.236 erg/cm(2)) and the blocking temperature (Tb) Of 260 degrees
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).
