我们研制成功了一种新型高压室，用于测量低温下磁场中的电阻率绝对值。这种压力池基于一种使用改进的布里奇曼顶锤和特氟隆胶囊的技术，可以产生至少高达6 Gpa的近静水压。这种压力室最重要的特点是其紧凑的机身，可以很容易地与超导磁体中的稀释式制冷机相结合。它的一个应用是在近静水压力下精确测量磁输运，这是通过对自旋梯形晶体Sr14−xCaxCu24O41(x=12)单晶的压力感生超导态的研究证明的。
We have succeeded in developing a new high-pressure cell designed for measuring the absolute value of the electrical resistivity in magnetic fields at low temperatures. This pressure cell, based on a technique using modified Bridgman anvils with a Teflon capsule, can generate nearly hydrostatic pressure at least up to 6 GPa. The most important feature of this pressure cell is its compact body which can be easily combined with a dilution refrigerator in a superconducting magnet. One of its applications is for precise magneto-transport measurements under nearly hydrostatic pressure, which is demonstrated by the investigation into the pressure-induced superconducting state of the spin-ladder Sr14−xCaxCu24O41 (x=12) single crystal.
