Query: Superconductivity at 6 K and the violation of Pauli limit in Ta2PdxS5   Ta2PdxS5 (x < 1.0) was found to show superconductivity at Tc ~ 6 K. The
temperature dependent resistivity of single crystalline Ta2Pd0.92S5 showed that
the system is strongly disordered due to Pd deficiencies and close to Anderson
localized state. Superconductivity in the dirty limit as well as the
temperature dependence of specific heat C(T) implies that superconductivity is
s-wave. The upper critical field Hc2 at T = 0 K limit with the magnetic field
parallel to the TaS6 chains was found to be as high as 31 T, exceeding the
Pauli paramagnetic limit Hp = 10.2 T by a factor of 3. We argue that the
absence of the paramagnetic pair-breaking originates from strong spin-orbit
scattering due to Pd deficiencies embedded in the periodic lattice of heavy 5d
Ta and 4d Pd.
