Šimić, Fran (author), Sharma, S. (author), Blanter, Y.M. (author), Bauer, G.E. (author)We propose and model a method to excite a large number of coherent magnons with high momentum in optical cavities. This is achieved by two counterpropagating optical modes that are detuned by the frequency of a selected magnon, similar to stimulated Raman scattering. In submillimeter-size yttrium iron garnet spheres, a milliwatt laser input...journal article 2020
