The effect of pressure on the electrical resistance and the magnetoresistance of (Fe 30 A/Cr 11 A)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 p decreases with increasing pressure, having a rate of (1/ p)(dp/dP)= - 8.7 x 10 3 kbar-1 at room temperature, and that the magnetoresistance (MR) ratio Ap/ps at 4.2 K is approximately constant below 8 kbar but decreases rapidly with increasing pressure above 8 kbar. The saturation field Hs increases with pressure.
