Abstract
It is shown that magnetic quantum states characterized by a toroidal moment of the same order of magnitude as the routinely measured molecular magnetization can arise in molecular wheels from the interplay between isotropic exchange and on-site magnetic anisotropy. They represent the first example of noncollinear molecular Néel states whose coupling can be strongly quenched as function of the orientation of the local anisotropy axes. © 2008 The American Physical Society.File in questo prodotto:
