• Abstract summary: Superconductors are materials with zero electrical resistivity and the ability to expel magnetic fields known as the Meissner effect. We use superconducting diamagnetism to shape the magnetic environment governing the transport of spin waves in a thin-film magnet. Our results demonstrate the versatility of superconductor-manipulated spin-wave transport and have potential applications in spin-wave gratings, filters, crystals and cavities.

• Abstract: Superconductors are materials with zero electrical resistivity and the ability to expel magnetic fields known as the Meissner effect. Their dissipationless diamagnetic response is central to magnetic levitation and circuits such as quantum interference devices. Here, we use superconducting diamagnetism to shape the magnetic environment governing the transport of spin waves - collective spin excitations in magnets that are promising on-chip signal carriers - in a thin-film magnet. Using diamond-based magnetic imaging, we observe hybridized spin-wave-Meissner-current transport modes with strongly altered, temperature-tunable wavelengths. We extract the temperature-dependent London penetration depth from the wavelength shifts and realize local control of spin-wave refraction using a focused laser. Our results demonstrate the versatility of superconductor-manipulated spin-wave transport and have potential applications in spin-wave gratings, filters, crystals and cavities.

  A superconducting quantum interference device is embedded in a microwave resonator and coupled via a pick-up loop to a magnetically-levitated superconducting sphere. The motion of the sphere in the magnetic trap induces a frequency shift in the SQUID-cavity system. The measured displacement sensitivity of $10-7, mathrmm / sqrtmathrmHz$, defines a path towards ground-state cooling of levitated particles with Planck-scale masses at millikelvin environment temperatures.

  We develop an in-situ magnetic detection technique at megabar pressures with high sensitivity and sub-microscale spatial resolution. We observe the macroscopic magnetic transition of Fe3O4 in the megabar pressure range from strong ferromagnetism (alpha-Fe3O4) to weak ferromagnetism (beta-Fe3O4) and finally to non-magnetism (gamma-Fe3O4) The presented method can potentially investigate the spin-orbital coupling and magnetism-superconductivity competition in magnetic systems.

  cavity photons and ferromagnetic spins excitations can exchange information coherently in hybrid architectures.

We show that the geometry of the ferromagnet plays also an important role, by setting the fundamental frequency of the magnonic resonator.
