摘要：

The effect of pressure on the electrical resistance and the magnetoresistance of (Fe 30 angstrom/Cr 11 angstrom)22 superlattices has been investigated at high pressures up to 16 kbar and high magnetic fields up to 50 kOe. It is found that the electrical resistivity rho decreases with increasing pressure, having a rate of (1/rho)(partial derivative rho/partial derivative P) = -8.7 x 10(-3) kbar-1 at room temperature, and that the magnetoresistance(MR) ratio DELTArho/rho(s) at 4.2 K is approximately constant below 8 kbar but decreases rapidly with increasing pressure above 8 kbar. The saturation field H(s) increases with pressure.
