“…Our experiment opens up a new path to study nonlinear effects in magnetic materials and spin ensembles. The mutual interaction between different magnetostatic modes in a single YIG sample can also provide new degrees of freedom for cavity spintronics and cavity magnonics [70]. We anticipate that this finding may stimulate more designs and applications of cavity magnonics.…”

When there is a certain amount of field inhomogeneity, the biased ferrimagnetic crystal will exhibit the higher-order magnetostatic (HMS) mode in addition to the uniform-precession Kittel mode. In cavity magnonics, we show both experimentally and theoretically the cross-Kerr-type interaction between the Kittel mode and HMS mode. When the Kittel mode is driven to generate a certain number of excitations, the HMS mode displays a corresponding frequency shift, and vice versa. The cross-Kerr effect is caused by an exchange interaction between these two spin-wave modes. Utilizing the cross-Kerr effect, we realize and integrate a multi-mode cavity magnonic system with only one yttrium iron garnet (YIG) sphere. Our results will bring new methods to magnetization dynamics studies and pave a way for novel cavity magnonic devices by including the magnetostatic mode-mode interaction as an operational degree of freedom.

“…Magnets have found commercial applications in magnetic field sensing and storing of information, and are a promising building block for long-range information transfer [1,2] and low-power logic devices [3]. Recently, there has been an interest in bringing such applications into the quantum domain, known as 'quantum magnonics' [4,5,6,7]. This is partly fuelled by the extremely low magnetic dissipation found in the ferrimagnetic insulator Yttrium Iron Garnet (YIG) [8], along with evidence for macroscopic (mm-long) coherence lengths [9,10].…”

Protocol for generating an arbitrary quantum state of the magnetization in cavity magnonics

We propose and numerically evaluate a protocol to generate an arbitrary quantum state of the magnetization in a magnet. The protocol involves repeatedly exciting a frequency-tunable superconducting transmon and transferring the excitations to the magnet via a microwave cavity. To avoid decay, the protocol must be much shorter than magnon lifetime. Speeding up the protocol by simply shortening the pulses leads to non-resonant leakage of excitations to higher levels of the transmon accompanied by higher decoherence. We discuss how to correct for such leakages by applying counter pulses to de-excite these higher levels. In our protocol, states with a maximum magnon occupation of up to ∼ 9 and average magnon number up to ∼ 4 can be generated with fidelity > 0.75.

We experimentally and theoretically demonstrate that nonlinear spin-wave interactions suppress the hybrid magnon-photon quasiparticle or "magnon polariton" in microwave spectra of an yttrium iron garnet film detected by an on-chip split-ring resonator. We observe a strong coupling between the Kittel magnon and microwave cavity mode in terms of an anti-crossing as a function of magnetic fields at low microwave input powers, but a complete closing of the anti-crossing gap at high powers. The experimental results are well explained by a theoretical model including the three-magnon decay of the Kittel magnon into spin waves. The gap closure originates from the saturation of the ferromagnetic resonance above the Suhl instability threshold by a coherent back reaction from the spin waves.
