Abstract :
Ferromagnetic resonance from two individual magnetic sublattices of ferromagnetic materials has been observed in the laboratory. Separate g-factor (gyromagnetic ratio) values were measured from the resonance experiment. A high signal-to-noise-ratio, millimeter-wave, broadband Fourier transform spectrometer and a high-intensity-field (140000-G) DC magnet were utilized for this measurement.<>
