This book highlights measurement methods for order parameters of quantum materials using electron spectroscopy. Quantum materials are a research hotspot in condensed matter physics. Their various phases and macroscopic properties are closely related to multiple order parameters in materials, including lattice, charge, spin, orbit, and topology. Modern advanced electron microscopy provides a powerful tool for characterizing the various order parameters and their correlation mechanisms of quantum materials at the atomic scale. On the basis of introducing the principles of electron microscopy, this book systematically describes how to use electron microscopy methods to measure and study the order parameters of quantum materials, and summarizes the results of order parameter measurement and synergistic research on multiferroic materials, magneto-optical materials, high-temperature superconducting materials, etc. This book is suitable for researchers and students engaged in the study of condensed matter physics, quantum science and technology, and materials science.
