- 論文の詳細を見る
Static and dynamic structure factors of' Heisenberg ferrimagnetic spin chains are numericallyinvestigated. There exist two distinct branches of elenuentary excitations, which exhiloit ferromag-netic and antiferronaagnetic aspects. The ferromagnetic feature is srtaeared out with the increaseof temperature, whereas the antif'erronaagnetic one persists 01) to higher tenaperattzres. The scattering intensity is remark?rbly large at lower botrndaries of' the f'errotauagnetic and antif'errornagnetic spectra. All these observations are consistent with the ferromagnetic-to-antif'errotnagneticcrossover in the thertnal behavior which has recently been reported.
