Abstract
We study mechanism of magnetic energy transport, motivated by recent measurements of the thermal conductivity in low dimensional quantum magnets. We point out a possible mechanism of enhancement of the thermal conductivity in gaped magnetic system, where the magnetic energy transport plays a crucial ro le. This mechanism gives an interpretation for the recent experiment of CuGeO$_{3}$, where the thermal conductivity depends on the crystal direction.
