Preyssler-type polyoxometalate(POM) has a cavity, in which various metal ions can be included. The POM possesses two stable ion sites located at the cavity center. Because it allows the included ion to move between two sites, POM exhibits the ferroelectric property on one molecule. Here, we investigated that POM included Ho ion, which has been reported as a single ion magnet, was measured its dielectric properties. We also developed the same mechanism for organic compound and aimed to expand the substance group.
