Metallic State in Rubidium-Loaded Low-Silica X Zeolite

Hyperfine couplings between the paramagnetic moment and nuclei in the metallic phase of low silica X zeolite loaded with potassium

“…1 Low silica X (LSX) is one of the representative zeolite substances exhibiting such a phenomenon. The metallic properties of such a substrate with sodium loading have been more extensively studied [2][3][4] than those with other alkali species as potassium, 5 rubidium, 6 and so on. It has been known that the metallic phase of the system is accompanied by a paramagnetic moment observed through susceptibility measurements, and the appearance of a separated component in the 23 Na NMR spectrum 3,7,8 has been detected.…”
