Abstract

The thermal conductivity and specific heat of SrCu₂(BO₃)₂, a quasi-two-dimensional metal oxide compound with a spin gap, were studied at low temperatures. In the temperature interval 0.4 < T < 3.2 K, the thermal conductivity of a single crystal sample in the ab plane varies according to the power law κ ∝ T^2.73. As the temperature increases further, a deep minimum is observed in the region of T_min ≈ 9.8 K. This behavior is explained by the scattering of phonons - the major heat carriers - on the fluctuations of the spin subsystem.
