While photon-based squeezing has been extensively studied, magnetic systems remain an untapped resource for squeezed-state engineering. Here, we demonstrate squeezing for magnetization dynamics in an yttrium iron garnet (Y3Fe5O12, YIG) film via microwave parametric excitation, achieving thermal squeezing. We also demonstrate thermal two-mode squeezing in the form of correlated fluctuations of magnons concentrated on the top and bottom surfaces of the YIG film. The unconventional magnetization highlights the promise of magnetic materials as a platform for quantum science in the foreseeable future.
