摘要：

Exchange couplings between antiferromagnetic Mn-Lr and ferromagnetic Ni-Fe layers have been investigated while varying the Mn-Ir composition. These exchange couplings appeared at room temperature at Lr compositions between 20 and 46 at.%. The maximum exchange coupling field of 3.2 kA/m was obtained for Mn-20 at.%Ir(59 nm)/Ni-Fe(2D nm)/Zr(10 nm). Dependence of the exchange coupling fields on each layer thickness was also investigated. The Mn-Ir/Ni-Fe bilayers maintained high exchange coupling fields at Mn-lr layer thicknesses above 10 nm.
