Effect of large in-plane magnetic field on the negative Hall states of (TMTSF)2ClO4

Orientation dependence of the negative Hall phase in (TMTSF) 2 ClO 4 was studied in presence of a large in-plane magnetic fields. Rotations within the b - c crystallographic plane reveal a highly anisotropic behavior in the magnitude of the negative Hall state. A discernible oscillation in the magnitude of the negative Hall states is observed as a function of angle. We identify the Lebed resonance associated with the commensurate electronic motion in the negative Hall state.
