Abstract : The ferrimagnetic resonance of the tight exchange coupled system was discussed in the light of the correlation method (theory of Kubo). The resonance field, H sub o (or resonance frequency) and the line width 2 delta w of the ferromagnetic branch, and also that of the exchange, were determined from a general magnetic susceptibility tensor formula. Results indicate that so-called fast relaxation and slow relaxation are but two branches (the transverse and longitudinal) of the ferromagnetic resonance. (Author)
