The magnetic susceptibility of the organic superconductors \ensuremathκ\ensuremath-(h8ord8\ensuremath-ET)2X, X=Cu(NCS)2 and Cu[N(CN)2]Br has been studied. A metallic phase below T*=37--38 K for X=Cu[N(CN)2]Br and 46--50 K for X=Cu(NCS)2 has an anisotropic temperature dependence of the susceptibility and the charge transport. Partial charge-density-wave or charge fluctuation is expected to coexist with the metallic phase instead of the large antiferromagnetic fluctuation above T*. The phase diagram and the superconductivity of \ensuremathκ\ensuremath-(ET)2X are discussed in connection with this phase.
