Abstract
Dependence of interlayer exchange coupling on antiferromagnetic IrMn thickness, thermal stability, and parallel anisotropy angle in perpendicular anisotropy [CoFe/Pt/CoFe]/IrMn multilayers was investigated. The magnetic property of [CoFe($10{\AA}$)/Pt($8{\AA}$)/CoFe($10{\AA}$)] induced by antiferromagnetic ordering of IrMn layer was maintained a stable perpendicular anisotropy up to $250^{\circ}C$ and from $7{\AA}$ to $160{\AA}$ of IrMn thickness. The value of interlayer exchange coupling of [CoFe/Pt/CoFe]/IrMn multilayers with perpendicular anisotropy increased to 1.5 times at anisotropy angle of $60^{\circ}$ more than of $0^{\circ}$. On the other side, the interlayer exchange coupling at anisotropy angle of $90^{\circ}$ was $\infty$ Oe, it was likely diverted to a parallel shape magnetization.
