Claim 4:
5. The method of claim 4, further comprising detecting the magnetostatic spin waves propagating through the ferromagnetic material, comprising:
providing a solenoid generating a bias magnetic field at a detection surface of the ferromagnetic material, where the bias magnetic field is parallel to a plane formed by a surface of the ferromagnetic material;
providing an detector radiofrequency resonator that resonates at frequencies corresponding to the FMR frequencies of the ferromagnetic material;
detecting a pulsed oscillating magnetic field coupled to the magnetostatic spin waves at the detection surface of the ferromagnetic material; and
converting the pulsed oscillating magnetic field into a detector radiofrequency signal.
