Magnetic Properties of Quantum Ferrimagnetic Spin Chains
Shoji Yamamoto
Abstract
Magnetic susceptibilities of spin-(S,s) ferrimagnetic Heisenberg chains are numerically investigated. It is argued how the ferromagnetic and antiferromagnetic features of quantum ferrimagnets are exhibited as functions of (S,s). Spin-(S,s) ferrimagnetic chains behave like combinations of spin-(S-s) ferromagnetic and spin-(2s) antiferromagnetic chains provided S=2s.
