摘要: The thermal conductivity of Sr2RuO4 along the least conducting direction perpendicular to RuO2 plane has been studied down 0.3 K. In this configuration phonons remain dominant heat carriers lowest temperature, and their in normal state is determined by scattering on conduction electrons. We show that phonon mean free path superconducting sensitive density quasi-particles bulk. An unusual magnetic field dependence ascribed anisotropic gap structure Sr2RuO4.
