Quantum sensing for nanoscale magnetic imaging

Nanoscale resolution of the properties of materials often plays a crucial role in the pursuit of explanations for exotic phenomena in such materials. These phenomena, such as high temperature superconductivity and frustrated magnetic states, have very exciting potential for practical applications, such as quantum computing. In the Sochnikov Lab, we use state-of-the-art sensors called SQUIDs to probe the magnetic properties of materials and generate magnetic maps at their surfaces. These images are on the order of micrometers in spatial resolution and play an important role in the study of the aforementioned phenomena, for example, because they can be used to analyze the formation and interaction of domains in response to parameters like temperature, auxiliary magnetic field, or strain. I will present some of the fundamental materials research work I have done in the Sochnikov Lab, in which I and my lab mates have taken a direct role in both measurement and analysis. In addition, I will share my experience with instrumentation development projects like the construction of custom-built piezoelectric scanners, the improvement of wiring in our cryostats, the coding of a GUI system for the plotting of data, and the improvement of our data interpolation functions.
