Low temperature electronic properties of Sr₂RuO₄ III: Magnetic fields

Original · EN

Based on the microscopic model introduced previously the observed specific heat and ac-susceptibility data in the superconducting phase in Sr₂RuO₄ with applied magnetic fields are described consistently within a phenomenological approach. Discussed in detail are the temperature dependence of the upper critical fields Hc₂ and H₂, the dependence of the upper critical fields on the field direction, the linear specific heat below the superconducting phase transition as a function of field or temperature, the anisotropy of the two spatial components of the order parameter, and the fluctuation field Hₚ.
