Abstract: A study is made of the spinon continuum fine structure which is observed to occur in the spin-liquid phases of chain- and triangular-lattice magnets at small wave vectors due to the action of a uniform Dzyaloshinsky–Moriya interaction. An ordered phase with a strongly quantum-reduced order parameter is found to exhibit the coexistence of magnon and spin type excitations, the former crossing over to the latter when the excitation energy exceeds that of the exchange interaction.
