Instability of square vortex lattice in d-wave superconductors is due to paramagnetic depairing

Abstract

Effects of the paramagnetic depairing on structural transitions between vortex lattices of a quasi two dimensional d-wave superconductor are examined. It is found that, in systems with Maki parameter ${\alpha }_{\mathrm{M}}$ of order unity, a square lattice induced by a d-wave pairing is destabilized with {\it increasing} fields, and that a reentrant rhombic lattice occurs in higher fields. Further, a weak Fermi surface anisotropy competitive with the pairing symmetry induces another structural transition near $H_{c2}$. These results are consistent with the structure changes of the vortex lattice in CeCoIn${}_5$ in $\mathbf{H}\parallel c$ determined from recent neutron scattering data.
