Precise measurement of angles between two magnetic moments and their configurational stability in single-molecule magnets
A key parameter for the low-temperature magnetic coupling of in dinuclear lanthanide single-molecule magnets (SMMs) is the barrier UFA resulting from the exchange and dipole interactions between the two 4f moments. Here we extend the pseudospin model previously used to describe the ground state of dinuclear endofullerenes to account for variations in the orientation of the single-ion anisotropy ax
