Orbital Effect for the Fulde-Ferrell-Larkin-Ovchinnikov Phase in a Quasi-Two-Dimensional Superconductor in a Parallel Magnetic Field

Abstract

We 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, $\lambda =l_{\perp }(H)/d$, is responsible for strength of the orbital effect, where $l_{\perp }(H)$ is a typical "size" of the quasi-classical electron orbit in a magnetic field and $d$ is the inter-plane 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.
