我们描述了一种微型金刚石砧细胞，可用于商用超导量子干涉装置（SQUID）磁力计，以检测施加压力超过100 kbar的磁性和超导跃迁。该细胞设计简单，但由超低磁化率材料制成，使我们能够在SQUID磁力计（通常为10(-7)emu）的全灵敏度下检测样品的磁矩变化。我们给出了使用该电池在压力和温度范围内检测铁磁性，反铁磁性和超导转变的例子
We describe a miniature diamond anvil cell that can be used in a commercial superconducting quantum interference device (SQUID) magnetometer to detect magnetic and superconducting transitions at applied pressures above 100 kbar. The cell is of simple design but constructed out of ultralow susceptibility materials that allow us to detect changes in the magnetic moment of the specimen at the full sensitivity of the SQUID magnetometer (typically 10(-7) emu). We present examples of the use of the cell to detect ferromagnetic, antiferromagnetic, and superconducting transitions at pressures and temperatures in the range of 0
