文摘

The temperature dependence of thermal conductivity of Sr2RuO4 is investigated by the Boltzmann equation approach. We consider both the isotropic and anisotropic gap energy in superconducting state in the absence and presence of low magnetic field, and obtain the temperature dependence of the components of thermal conductivity in both cases. In the case of isotropic gap, it is proportional to T 1/2, whereas in the case of anisotropic gap, K xx ?em class="a-plus-plus">T ?,K yy ?em class="a-plus-plus">T, and K xy =K yx =constant. Furthermore, we show that at a low magnetic field K behaves as in the case of the zero magnetic field.
