Until recently it has been believed that the superconductivity in Sr2RuO4 is described by p-wave pairing. However, both the recent specific heat and the magnetic penetration depth measurements on the purest single crystals of Sr2RuO4 appear to be explained more consistently in terms of f-wave superconductivity. In order to further this hypothesis, we study theoretically the thermodynamics and thermal conductivity of f-wave superconductors in a planar magnetic field. We find the simple expressions for these quantities when H≪Hc2 and T≪Tc, which should be readily accessible experimentally.
