We predict that large moments J , placed into a crystal field with the cubic point symmetry group, differ in their spectrum and magnetic properties. E.g. , properties of the odd-integer moments are different from those of the even-integer. The effect is due to Berry's phases gained by the moment, when it tunnels between minima of the external field. Two cases of the group O are classified, namely, 6- and 8-fold coordinations. The spectrum and degeneration of energy levels depend on a remainder J / n , where the divisor n = 4 and 3 for the 6-fold and 8-fold coordination, respectively. Large spins in the cubic environment of the 6- and 8-fold coordinations can be realized by diluted alloys R 1 − x R x 'Sb, where R = Lu, La, Y, and R' = Er, Sm, Ce, Dy, Pm, Yb.
