Prof. Alexander Pyatakov, • M.V. Lomonosov Moscow State University, Physics Faculty • Title: Magnetoelectric and multiferroic media: rich physics behind, and promise for multipurpose applications • Abstract: This lecture introduces students to the concept of magnetoelectricity as opposed to conventional electromagnetism: the basic physical effects underlying the mutual conversion of electricity and magnetism, as well as the promising multipurpose application from ultra-low energy electronics to neuromodulation. • Main paper/arXiv, related to the seminar, and other references: • 1.
