标准磁强计的改进型电输运探头设计
Modified electrical transport probe design for standard magnetometer
摘要：
在材料上进行电输运测量通常是一个耗时的过程，涉及测试大量样品。因此，将样品布线和重新布线到样品探针上是不方便的。因此，我们提出了一种修改量子设计的MPMS SQUID磁强计运输探头，简化了样品安装过程的方法。要克服的困难之一是样品空间的小直径。探头上设计并安装了一个小插座，以便在插座中轻松更换安装在各个头上的各种样品。我们也给出了用改进的探针对拓扑绝缘体Bi_2Te_2Se的测试结果。
英文摘要：
Making electrical transport measurements on a material is often a time consuming process that involves testing a large number of samples. It is thus inconvenient to wire up and rewire samples on to a sample probe. We therefore present a method of modifying Quantum Design's MPMS SQUID magnetometer transport probe that simplifies the process of sample mounting. One of the difficulties to overcome is the small diameter of the sample space. A small socket is designed and mounted on the probe so that various samples mounted on individual headers can be readily exchanged in the socket. We also present some test results on the topological insulator Bi2Te2Se using the modified probe.
