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 ρ decreases with increasing pressure, having a rate of (1/ρ)(∂ρ/∂ P )=-8.7×10 -3 kbar -1 at room temperature, and that the magnetoresistance (MR) ratio Δρ/ρ 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.
