Magnetic resonance of spinons in quantum magnets


Kapitza Institute of Physical Problems, Russian Academy of Sciences, ul. Kosygina 2, Moscow, 117334, Russian Federation

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 Dzyaloshinskii—Moriya interaction. An ordered phase with a strongly quantum-reduced order parameters is found to exhibit the coexistence of magnon and spin excitations, the former crossing over to the latter when the energy exceeds that of the exchange interaction.
