The Critical Behaviour of Pyroelectric-Type Superconductors

The quasiclassical, Eilenberger-type equations are applied to description of rotating P-wave pyroelectric-type superconductor in the presence of magnetic field H and superflow υ. In analogy to type-II superconductors the possibility of vortex solution is discussed. We determine the symmetry of eigensolutions and the upper critical velocity Ω$\text{}_{c2}$. We discuss the paramagnetic critical behaviour of the system depending on the strength of spin-orbit interaction.
