Abstract

Some results in sandwiched Co/spacer/Co structures have been achieved. With doping Mn and NiO in the Cu spacer, the GMR curve as a function of the magnetic field changes a lot, and the saturation/switching field for GMR can be reduced greatly compare with that in Co/Cu/Co systems. The most important characteristic of the MR change for Co/CuMn/Co system was its two peaks became narrow and sharp, but for Co/NiO-Cu/Cu system, was its two peaks became wide and flat. These results may indicate some new ways in consideration of candidates for novel magnetic devices.
