Strong coupling between magnons and microwave photons has recently been theoretically proposed [1] and experimentally investigated using both microwave transmission [2-4] and electrical detection methods [5]. These works build the foundation for the emerging field of Cavity Spintronics [6], where the development of spintronics merges with the advancement in cavity quantum electrodynamics and cavity polaritons, thereby creating new theoretical and experimental avenues for studying wave physics, developing quantum technology, and facilitating spintronics applications.

Based on the remarkable achievements of the pioneers of Cavity Spintronics, this talk aims to provide a brief introduction of this exciting new frontier of condensed matter research to colleagues working on magnetism, spintronics, and microwave technologies. Related work recently done by our group at the University of Manitoba will be reported [5-8].
