An easy-to-use and versatile software to calculate spin waves in any abitrary magnetic lattice.
Since the 1950’s, spin wave theory has been of fundamental importance in condensed matter physics. Spin waves are obtained from the linearization of the equation of motion, and can be seen as precession modes of the magnetically ordered structure, with typical energies of a few meV (or THz). Spin wave dispersions are routinely measured by neutron spectroscopy, and provide information about the coupling between spins and magnetic anisotropy parameters.
A spin wave calculating code, SpinWave, has been developed at the Laboratoire Léon Brillouin and is now freely available.
