  • Abstract
    Cu/Co/Cu/NiFe multilayer films prepared by evaporation deposition in an ultrahigh vacuum were heat-treated in air and in ultrahigh vacuum. Heat treatment in ultra-high vacuum brought about no changes in the MR ratio or MR slope for annealing temperatures less than 400C. The thermal stability in air was limited by gradual oxidation from the surface, and thermal stability up to 250°C was verified. Improved thermal stability was achieved by the use of thicker NiFe layers.
