Abstract

The nature of the spin density wave (SDW) and charge density wave (CDW) in the mixed state of high-Tc superconductors (HTS) is investigated by using the self-consistent Bogoliubov-de Gennes equations and an effective model Hamiltonian with competing SDW and d-wave superconductivity interactions. We show that there exists a critical on-site Coulomb interaction Uc. For optimally doped sample, two-dimensional SDW and CDW modulations are induced for U < Uc while SDW and CDW orders become antiferromagnetic (AF) and charge stripes for U > Uc. These stripe orders are stabilized and enhanced near the vortex cores. The wave-lengths of the AF stripes and charge stripes are found respectively to be 8a and 4a, with a as the lattice constant. We show that our results could be applied to understand several recent experiments on HTS.
