Abstract
Quantum tunneling in nanomagnets finds a natural description in terms of intermediate spin. Periodic magnetic effects correspond to a change of flux by the flux quantum . Schrödinger cat states with different superpositions of the applied magnetic field occur. The molecular magnet is discussed and new effects are predicted for .
