Pulsed Field Studies of Angular Dependence of Unconventional Magnetoresistance in (TMTSF)2ClO4
Abstract
The field and angle dependence of magnetoresistance of (TMTSF)2ClO4 was studied by a pulsed magnetic field system up to 40 T. The third angular effect of this quasi-one-dimensional metal was clearly observed as well as Lee-Naughton oscillations with small amplitude for ab-plane rotation of the magnetic field. Saturating behavior of the field dependence of the magnetoresistance at a local minimum of the angular dependence contrasts with non-saturation (or divergence) at general field orientations to the crystal. This unconventional behavior may be explained by crossover of electronic system from one- to two-dimensional suggested by recent theories based on quantum mechanics.
