Magnetic Torque Measurements of the Organic Superconductor (TMTSF)2ClO4 with a Piezoelectric Cantilever

Since the discovery of the Bechgaard salts a quarter century ago, its fascinating physical properties opened a new horizon of the low-dimensional condensed matter physics. But there are still many interesting properties only partially understood or not understood at all. The high magnetic field state of the title compound, following the integer quantum Hall effects, is one o
