The second of three reports on superconductivity, this examines laboratory techniques for obtaining high pressures and their effects on the superconducting properties of materials. (The first, R-1401, treated high-temperature superconductivity; the third will discuss high-field superconductivity.) An assessment of U.S. and Soviet research in high-pressure superconductivity (HPS) based on a comprehensive coverage of open-source literature from 1971 through June 1974. Megabar pressure capability is at hand, thanks to development of very hard structural materials. Experimental data are copious, although the pressure range is limited and volume parameters are almost lacking. Soviet HPS research appears to be materials-oriented, American more academic. Hydrogen metallization under superhigh pressure is of major interest in the Soviet new materials program. HPS research has placed the USSR in a position of major strength in this field. 33 pp. Ref.
