Abstract

We investigated the magnetic properties of the Co1-xFe x-natural oxidized nano-oxide layer (NOL) in the specular spin-valve system by precise measurement of magnetization at 77 K and M-T curves after field cooling at ±5 kOe. The result suggests the antiferromagnetic component behavior of the NOL and its Néel temperature (TN) shifts to the higher temperature with increasing Fe composition. Below the TN, the antiparallel spin configuration at the pinned layers is stabilized by the exchange bias field induced from antiferromagnetic component of NOL by the field cooling in negative field direction.
