Outline of Final Research Achievements

In this study, we are aiming at realizing microwave-to-optical photon conversion through ordered spins in ferromagnetic materials, which embrace both merits of collectively enhanced interaction typically realized with the paramagnetic spin ensemble and rigidity against nearest neighbor unwanted interaction. We achieved 1) the coherent and bidirectional conversion between microwave and optical photons through magnons in a magnetostatic mode of a ferromagnetic sphere, 2) pioneering a new research field called "cavity opto-magnonics" to enhance photon-magnon coupling, and 3) understanding the origin of peculiar non-reciprocal interaction between photons and magnons in the setting of cavity opto-magnonics.
