Abstract
We report the first observation of a large pressure-induced enhancement of the giant magnetoresistance (GMR) in magnetic multilayers (MMLs). In Fe/Cr MMLs with a Cr layer thickness ( t Cr ) of ∼30 A, a crossover from biquadratic to bilinear interlayer exchange coupling (IEC) was clearly observed by applying pressure and simultaneously the GMR under high pressure (>2 GPa) was enhanced to be twice as large as that at ambient pressure. The enhanced GMR is attributed to the suppression of the biquadratic IEC due to the application of pressure.
