Abstract
We present an angle dependent study of the quantum Hall effect in the field-induced spin-density-waves of the organic conductor (TMTSF)2ClO4. Hall resistance remains quantized until the magnetic field makes more than 60° with the c* axis in the b′c* -plane. Most of the successive first order transitions are split into two upon tilting the sample, of which the mechanism is different from that of magnetocalroric splitting. We discuss these results in terms of multiple order parameters and the interferences between two pairs of Fermi surfaces.
