Outline of Final Research Achievements

K clusters arrayed in zeolite A are known to show ferromagnetic properties although they contain no magnetic elements. We synthesized a much amount of high quality sample and performed neutron diffraction experiments. We obtained magnetic diffraction data of this material for the first time. The Q-dependence of the magnetic form factor was examined. The results clearly indicate that the electrons delocalized over a nanometer size are responsible for the long-range magnetic order. We also found a periodic modulation of the size of the ferromagnetic moments. The obtained results are very fundamental and indispensable for understanding the mechanism of the magnetic ordering in the s-electron system.
