Spin dynamics of an ultra-small nanoscale molecular magnet

<p>Abstract</p><p>We present mathematical transformations which allow us to calculate the spin dynamics of an ultra-small nanoscale molecular magnet consisting of a dimer system of classical (high) Heisenberg spins. We derive exact analytic expressions (in integral form) for the ti...
