Scientific paper

We study the effects of magneto-elastic coupling on the degenerate ground state of the antiferromagnetic Heisenberg model on regular triangle and tetrahedron clusters of spin-1/2. Both give very similar results. Static distortion lifts the degeneracy of the ground state through the distance dependence of the exchange coupling. On the contrary, quantum-mechanical or dynamical distortion does not. The tetragonal distortion at the non-magnetic phase transition of spinels is discussed.
