Abstract

Spin-electric interactions and magnetic and magnetoelectric properties of the ${\mathrm{Dy}}4$ ring molecular nanocluster are investigated. The effective spin-electric Hamiltonian is derived on a base of developed quantum mechanical model of the cluster spin structure. It is shown that the toroidal moment is a source of the quantum magnetoelectric effect. The dynamics of the toroidal moment (macroscopic quantum tunneling) is also discussed.
