Project Description: Superconducting Quantum Interference Devices (SQUIDs) are among the most sensitive magnetic field sensors that we know. We are building a microscope that scans a SQUID close to a surface of a sample to obtain images of a sample’s magnetic properties. We use this technique to study a variety of quantum materials including topological insulators, van der Waals materials and unconventional superconductors. In this project, the REU student will work with graduate students and faculty to learn how to operate our low-temperature scanning SQUID microscope. The student will gain experience in remote instrument control, image analysis and low noise transport measurement techniques.
