The present invention discloses a method and application for generating a frequency comb based on superstrong coupling of magnons and magnons, which belongs to the field of spin electronics technology. In a system of two superstrongly coupled magnons, when a pumping magnetic field with a frequency close to the frequency of the high-frequency branch magnon is applied, the system enters a nonlinear state.
