摘要：

We have performed a torque magnetometry study of an organic superconductor. The results indicate that the superconductivity of -BEDT-TTF2Cu(NCS)2 is extremely anisotropic, and suggest a lower bound of 4×104 for the superconducting effective-mass anisotropy. Our data have also allowed us to make a detailed test of the predictions of the three-dimensional (3D) model for the torque and also those of a recently suggested 2D approach. Our results are in better agreement with the predictions of the 3D model. © 1990 The American Physical Society.
