EFFECT OF PRESSURE AND TEMPERATURE ON THE ELECTRICAL RESISTANCE OF ELEVEN RARE-EARTH METALS

;
The electrical resistance of eleven rare-earth metals was measured as a function of pressure to over 500 kbars at 77 and 296 deg K. Appropriate isobars between 77 and 296 deg K were also obtained. The electronic structure of rare- earth metals is complex with the 4f and 5d atomic levels relatively close, and both atomic levels split by the crystal field. A wide variety of transitions are observed, many of which must be electronic in character, i.e., they must involve the lowering in energy of one electronic energy band vis-a-vis another with increasing pressure and decreasing interatomic distance. These data should provide a partial basis for a theoretical treatment of energy bands in the rare- earth metals. (auth)
