Effect of the magnetic field orientation on specific heat of an exotic superconductor
The discovery of superconductivity is strontium ruthenate [1] and subsequent proposal of its spin triplet odd parity symmetry [2] has triggered a lot of experimental and theoretical activities [3]. One of the issues of great importance is the identification of the pairing symmetry of this superconductor. The effect of magnetic field on specific heat of a p-wave spin triplet superconductor has been analyzed. To describe superconductivity we used a single band model with various realizations of p-wave order parameter and analyzed the effect of a Doppler shift in different temperatures [4].
