Abstract

The giant magnetoresistance (GMR) of T/Cu (T = Fe, Co) magnetic multilayers (MML) has been investigated under high pressure at 4.2, 77 K and room temperature. It is found that the magnitudes of GMR at 77 K and at room temperature for both MMLs are almost independent of pressure up to 0.8 GPa, but 9.2% decrease in GMR is observed at 4.2 K under the pressure of 2 GPa. On the basis of these results, the difference between GMR for Fe/Cu and Co/Cu MMLs under high pressure is discussed briefly.
