Abstract
The direct and indirect correlation between organic radicals in a quas i-one-dimensional organic ferromagnet model is investigated. By introd ucing random-phase-approximation (RPA), the typical spin-wave excitati on modes of the model are obtained. The stiffness of acoustic spin-wav e mode is found to represent the correlation between radicals. The var iation of the stiffness according to the parameters of the system is d iscussed and indicates the unique features of the organic ferromagnet. Copyright (C) 1996 Elsevier Science Ltd
