Magnon-phonon interaction and kinematic spin-wave levels

The kinematic interaction of spin-waves is found to lead to additional energy levels even in the presence of an interaction of spin-waves with mechanical vibrations of the crystal molecules. Those levels appear in the region of large wave-vectors k > 10 7 cm −1. The lower limit of this interval i...

Description
Summary:The kinematic interaction of spin-waves is found to lead to additional energy levels even in the presence of an interaction of spin-waves with mechanical vibrations of the crystal molecules. Those levels appear in the region of large wave-vectors k > 10 7 cm −1. The lower limit of this interval is defined by the intensity of the magnon-phonon interaction.
