Abstract(in English) | We compared specular spin-valve films with an Fe^<50>Co^<50> nano-oxide layer(NOL) and a Co^<90>Fe^<10> NOL in a pinned layer,prepared by natural oxidation and ion-assisted oxidation(IAO).With small oxygen exposures during the oxidation for the Fe^<50>Co^<50>NOL by IAO,good ferromagnetic coupling through the NOL and high specularity at the NOL interface were concurrently obtained.On the other hand,natural oxidation did not cause large MR enhancement for either the Co^<90>Fe^<10> or Fe^<50>Co^<50>NOLs,and the Co^<90>Fe^<10> NOL by IAO caused weak magnetic coupling through the NOL,resulting in a small MR ratio.The Fe^<50>Co^<50>NOL for small oxygen exposures is a good candidate for a final specular spin-valve film head for 100-Giga-bit per square inch recording. |
