| Abstract: |
The loading density n dependence of the hyperfine coupling constant A between Na and uniform susceptibility in the cage was examined using Na NMR spectra for Na-K form low-silica X zeolite loaded with potassium. As n increased and ferrimagnetic ordering disappeared, A grew several times larger. This can essentially be understood as an enhancement of the hyperfine interaction among the cages, owing to the denser electron condition. Other than such the effect, it is pointed out that a transitional change in local susceptibility may occur among the cage and the supercage, following the change of n. [ABSTRACT FROM AUTHOR] |
