中文摘要	Magnetic states of the system described by a Heisenberg-like model with on-site spin fluctuation are studied. Two features are shown for such a system. One is that the system may reveal ferromagnetism or antiferro-magnetism in the intermediate temperature range between zero and order-disorder transition temperature. The other is that there may occur a first-order transformation below order-disorder transition temperature. These are effects of on-site spin fluctuation.
