Claim 0:
1. A method for exciting magnetostatic spin waves in a ferromagnetic material having ferromagnetic resonance (FMR) frequencies, comprising:
providing a solenoid generating a bias magnetic field at an excitation surface of the ferromagnetic material, where the bias magnetic field is parallel to a plane formed by a surface of the ferromagnetic material; and
providing an exciter radiofrequency resonator, converting an exciter radiofrequency signal having a frequency equal to the resonant frequency of the exciter radiofrequency resonator into a pulsed oscillating magnetic field,
wherein the pulsed oscillating magnetic field is defined by a vector orthogonal to a vector defined by the bias magnetic field, and
wherein the pulsed oscillating magnetic field excites magnetostatic spin waves in the ferromagnetic material.
