Probing Local Magnetic Field Patterns

In this webinar, Jelena and Prof. Martino Poggio (University of Basel) look into how macroscopic manifestations of quantum mechanics involving strongly correlated states, e.g. superconductivity and magnetism, are sensitive to the local environment. Nanometer-scale spatial resolution is often required to identify the conditions for the emergence of such macroscopic behaviors. Martino talks about the basic principles and applications of magnetic imaging techniques, including NV-center and nano-wire MFM microscopy, that shed light on magnetization patterns, spin configurations and current distributions. Jelena shows how lock-in amplifiers can be used with such local probing techniques to enhance their sensitivity and contrast. In this blog post, Jelena answers the questions asked during the live session.
