论文摘要
我们已经使用微型3HE低温恒温器和一个闭合周期的3HE气体处理系统进行了精确的磁化测量，用于商业超导量子量子干扰器件磁力计[磁性属性测量系统（量子设计）]。气体处理系统包含两个装有颗粒状木炭的吸附泵。我们将3HE气体加压到3 K时液化的环境压力，然后泵送Vaper进行冷却。最低样品温度约为0.5 K，可以持续34小时。我们通过观察超导过渡温度下方的铝的Meissner效应〜1 K。
We have conducted precise magnetization measurements down to 0.5 K with a miniature 3He cryostat and a closed-cycle 3He gas handling system for a commercial superconducting quantum interference device magnetometer [Magnetic Property Measurement System (Quantum Design)]. The gas handling system contains two sorption pumps filled with granular charcoals. We pressurize 3He gas up to ambient pressure for the liquification at 3 K and then pump the vaper for cooling. The lowest sample temperature is ~ 0.5 K and it can persist for 34 hours. We demonstrate the performance of the system by observing the Meissner effect of aluminum below the superconducting transition temperature ~ 1 K. We also measured the magnetization curve of the heavy fermion superconductor CeCoIn5 resulting in successful observation of the lower critical field at 0.5 K.
