Quasi-one-dimensional (Q1D) organic conductors with simple open Fermi surfaces have provided novel angular dependent magnetoresistance oscillation (AMRO) phenomena for the last two decades. Both semiclassical and quantum mechanical theories well explain these phenomena, but detailed study of the field dependence probably gives a crucial test. Recently it was proposed that a kind of AMRO that is known as "Lee-Naughton oscillations (LNO)" observed for (TMTSF)2ClO4 is a result of dimensional crossover of electronic system from oneto two-dimension on changing the field orientation. We have studied the field dependence of the magnetoresistance of Q1D superconductors (TMTSF)2ClO4 and (DMET) 2I3by using a 46-T pulsed magnetic field system and found the B1/2-behavior at minima of LNO.
