摘要：

The structural and magnetic properties of potassium-loaded zeolite LTA, K-x-K12Si12Al12O48, were studied as a function of the loading density, x, up to similar to 7. We observed a superlattice that develops with increasing loading density, and which is correlated with the low-temperature (T) magnetic phases. It was found that the ferromagnetic-like moment appearing at low T's coexists with lattice modulations such as the mass density wave or the charge density wave.
