A new theory of the magnetism at finite temperatures which takes accountof the local environment effect and can describe the glass-like phase (GLP) isformulated by using the functional integral method combined with the methodof the distribution function. The theory is applied to the NiMn alloy, and thelocal magnetic moments in various environments are calculated as the functionsof the temperature, the concentration and the atomic short range order. TheCurie temperature and the freezing temperature are also obtained. Anomalousbehaviours such as the temperature-induced magnetization and the stronglyvariable magnetization with the atomic ordering in NiMn are explained for thefirst time by the present theory of itinerant-electron systems.
