- 論文の詳細を見る
The effect of pressure on the electrical resistance and the magnetoresistance of (Fe 30Å/Cr 11Å)_<22> superlattices has been investigated at high pressures up to 16 kbar and high magnetic fields up to 5O 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.
