摘要：
A 2D LOFF model for the clean superconductor λ-(BETS)2FeCl4 was used to calculate the Hc2(T) curve for the orientation of the magnetic field parallel to the layers. The exchange field induced by Fe3+ polarized magnetic moments was taken into account. It was shown that accounting for the 2D LOFF state improves fitting at low temperatures in comparison with the 3D model. A cascade of first-order transitions of the vortex lattice was observed.
