The physical properties of organic superconductors under a magnetic fi
eld are advances in theories for phenomenology, the superconductivity
transitions of BEDT-TTF salts and A3C60 are analyzed by taking account
of fluctuation, and thereby the physical parameters are reevaluated,
while (TMTSF)2X can be treated by an anisotropic effective mass tensor
model. Other properties relevant to vortex dynamics and paramagnetic
pair breaking effect are also mentioned.
