Abstract:
A new technique for measuring the magnetization of materials over a wide range of pressures and temperatures was developed. Because of its high sensitivity, this technique opened up a new field The pressure dependence of weak metallic susceptibilities. The technique employs a Faraday magnetometer, miniature pressure clamps, and a novel method for compensating the background magnetization of the clamps. Emphasis was placed on pressure-induced magnetic-nonmagnetic transitions in metals. These were documented for the first time by magnetic measurements on certain rare earth metals, their alloys and compounds, and itinerant ferromagnets. As a result of this work, a new class of nonmagnetic rare earth materials with nonintegral valence was recognized. Author
