摘要：

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 similar to combinations of spin-(S-s) ferromagnetic and spin-(2s) antiferromagnetic chains provided S=2s. [S0163-1829(99)15701-1].
