| Research Abstract |
Zeolite LSX hasβ-cages and supercages with the inside diameters of 0. 7 and 1. 3 nm, respectively. They are arrayed in a double diamond structure. Na-K alloy nanoclusters arrayed in the zeolite LSX show a ferrimagnetic ordering although they contain no magnetic element. This work has clarified the magnetic phase diagram with very wide area of Na-K composition and the electron densities, and proposed a plausible model of the mechanism of the ferrimagnetic ordering.
