dc.descriptionIt is shown that interference effects between velocity and density of states, which occur as electrons move along open orbits in the extended Brillouin zone, result in a change of wave functions dimensionality at Magic Angle (MA) directions of a magnetic field. In a particular, we demonstrate that these 1D -> 2D dimensional crossovers result in the appearance of sharp minima in a resistivity component Rzz, perpendicular to conducting layers, which explains the main qualitative features of MA and Angular Magneto-Resistance Oscillations (AMRO) phenomena observed in low-dimensional conductors (TMTSF)2X, (DMET-TSeF)2X, and a-(BEDT-TTF)2MHg(SCN)4.
