Heisenberg Linear Chain Magnets with Unlike Spins —An Exactly Soluble Model—

Hisao Okamoto, Katsuhiko Nagano, Tahashi Karasudani

    Research output: Contribution to journalArticlepeer-review


    The free energy, susceptibility and correlation functions for a linear chain of N+1 spins with unequal nearest-neighbor isotropic Heisenberg couplings due to two unlike spins randomly distributed on the chain are calculated explicitly in the (classical) limit of infinite spin. The temperature and concentration dependence of susceptibility are given in comparison with that for one-component systems.
