摘要：

K and Na clusters are generated in zeolite FAU with an Si-to-Al ratio of 1.25. We measured magnetic susceptibility, electron-spin resonance spectrum and the optical one. Observed magnetic properties are discussed from the viewpoint of the correlated electrons and/or the narrow energy band with a properly localized nature of clusters, together with a finite disorder effect.
