Anomalous In-Plane Anisotropy of the Onset of Superconductivity in (TMTSF)_2ClO_4

摘要

We report the magnetic-field amplitude and field-angle dependence of the superconducting onset temperature T_c~(onset) of the organic superconductor (TMTSF)_2ClO_4 in magnetic fields H accurately aligned to the conductive ab' plane. We revealed that the r
