Abstract

The effects of magic angle (MA) and magnetoresistance oscillations as dimensional crossovers, were investigated. The interference effects between velocity and density of states, which occur as electrons move along open orbits in the Brillouin zone in anisotropic conductors, were observed to change the dimensionality of wave function at MA directions. It was observed that 1D → 2D dimensional crossovers resulted in appearance of sharp minima. The results show that MA and angular magnetoresistance osciilations occurred due to the existence of quai-one-dimensional sheets of Fermi surface.
