AbstractWe theoretically study the orbital destructive effect against superconductivity in a parallel magnetic field in the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO or LOFF) phase at zero temperature in a quasi-two-dimensional (Q2D) conductor. We demonstrate that at zero temperature a special parameter, lambda = l(perpendicular to)(H)/d, is responsible for strength of the orbital effect, where l(perpendicular to)(H) is a typical "size" of the quasiclassical electron orbit in a magnetic field and d is the interplane distance. We discuss applications of our results to the existing experiments on the FFLO phase in the organic Q2D conductors kappa-(ET)(2)Cu(NCS)(2) and kappa-(ET)(2)Cu[N(CN)(2)]Cl.
