We experimentally study the tunability of the cooperativity in coupled spin--cavity systems by changing the magnetic state of the spin system via an external control parameter.

We experimentally demonstrate the formation of room-temperature skyrmions with radii of about 25\, nm in easy-plane anisotropy multilayers with interfacial Dzyaloshinskii-Moriya interaction (DMI).

We investigate the injection of quasiparticle spin currents into a superconductor via spin pumping from an adjacent FM layer.$\;$To this end, we use NbN/\ch{Ni80Fe20}(Py)-heterostructures with a Pt spin sink layer and excite ferromagnetic resonance in the Py-layer by placing the samples onto a coplanar waveguide (CPW).
