Abstract

We suggest a unified theory to describe unconventional magnetic properties of metallic, superconducting, and Field-Induced Spin(Charge)-Density-Wave [FIS(C)DW] phases in organic conductors with open sheets of Fermi surface. It is based on ideas about 3D → 2D, 3D → 1D, and 1D → 2D dimensional crossovers for electron spectra and wave functions, which occur due to quantum interference effects when electrons move in a magnetic field in the extended Brillouin zone. Our theoretical results are applicable to quasi-one-dimensional (Q1D) compounds in an arbitrary inclined magnetic field and to quasi-two-dimensional (Q2D) compounds in a parallel magnetic field. Using the above mentioned approach, we describe Lebed Magic Angle and Interference Commensurate oscillations in a metallic phase, FIS(C)DW phase diagrams, the Reentrant Superconductivity phenomenon, and some other non-trivial magnetic effects.
