The semi-collinear interaction between optical waveguide modes and backward volume magnetostatic waves

Strong Coupling of 3D Cavity Photons to Travelling Magnons At Low Temperatures

“…In this work, we consider epitaxial YIG films, a well established crystal growth technology, as a building block for spectrally pure magnonic parts of QED systems and associated perspectives in applications of this material in low temperature physics. Utilisation of YIG material in the form of films is also motivated by the fact that it has been employed as a platform to study nonlinear effects in magnetic systems 15,16 , magnetooptical phenomena [17][18][19][20] , light/microwave interaction 21 , Bose-Einstein condensates of magnons 22 , transport phenomena 23 as well as magnon-photon coupling properties of YIG films have been studied in microwave regime at room temperature [24][25][26] . Moreover, it has been proposed theoretically that magnetic films in 3D cavities and gratings may result in some interesting effects 27,28 .…”
