## Description

- description: Temperature dependences of NMR spectra have been observed for 23Na
    and 27Al in the metallic phase of Na–K form low silica X (LSX) zeolite loaded
    with potassium, where the condition of saturation is achieved with a loading level
    of 9.0 atoms per supercage and the paramagnetic moment contributes to the magnetism
    of the system beyond simple isolated spin. Two separated peaks have been recognized
    for 23Na, where the shift values show a quite linear relationship with susceptibility,
    and the so-called K–χ plot works quite well to give values of 0.32 kOe/μB and
    0.40 kOe/μB for hyperfine coupling constants. Although no separated peak is seen
    in the 27Al NMR spectrum, the spectral centroid deviates to the positive side.
    The shoulder of the spectrum scales to susceptibility and the K–χ plot also works
    well to give a value of 0.15 kOe/μB for the hyperfine coupling constant. The orbital
    of potassium-originated electrons confined in the cage of LSX is understood as
    seeping out over the framework of zeolite, which is wider than that of the sodium-originated
    case.
