Abstract

A new type of hydrostatic pressure cell is discussed. It is suitable for precise electrical and magnetic measurements on several samples simultaneously over a wide range of temperature and pressure. Pressures as high as 90 kilobars have thus far been reached in a four-point electrical resistivity measurement. These studies indicate minimal pressure changes upon cooling from 300 to 1 K, good pressure homogeneity, and absence of significant shear stresses.

摘要

讨论了一种新型的静水压力室。它适用于在很宽的温度和压力范围内同时对多个样品进行精确的电学和磁学测量。在四点电阻率测量中，目前已达到高达90千巴的压力。这些研究表明，从300 K冷却到1 K时压力变化极小，压力均匀性良好，且不存在明显的剪应力。
