纳米流体样品的微线圈核磁共振检测
Micro-coil detection of Nuclear Magnetic Resonance for nanofluidic samples
摘要：
我们开发了一种新型的直流SQUID系统，该系统具有微线圈输入电路，可作为量子物质和纳米系统的局域探针。平面铌微线圈拾取回路位于远离SQUID的位置，通过超导双绞线耦合，使样品处于微开尔文温度。可以实现线圈与相似尺寸（高达~ 100微米）的感兴趣区域之间的高度耦合。我们报告的核磁共振（NMR）测量，以验证这些线圈的灵敏度在气相中的3 He在4.2 K，在30 mT的磁场。
英文摘要：
We have developed a novel dc SQUID system with a micro-coil input circuit to act as a local probe of quantum matter and nanosystems. The planar niobium micro-coil pickup loop is located remotely from the SQUID, coupled through a superconducting twisted pair, enabling the sample to be at microkelvin temperatures. A high degree of coupling between the coil and the region of interest of similar dimensions (up to ~ 100 microns) can be achieved. We report nuclear magnetic resonance (NMR) measurements to characterise the sensitivity of these coils to 3He in the gas phase at 4.2 K in a 30 mT magnetic field.
