van der Waals magnetic materials, which retain magnetism down to a single two-dimensional layer of atoms, have great technological potential for spin-based information processing, however, typical approaches to measure their spin dynamics are often hampered by the small number of spins in a single atomic layer compared to three dimensional materials. Here, Zollitsch et al present a methodology for the detection of spin dynamics in van der Waals magnets via photon-magnon coupling between it and a superconducting resonator, with potential to resolve spin dynamics down to a single monolayer.
