23. for x>0, vapor-grown crystals show a lower Tc than polycrystalline samples, which has been attributed to a lower content of Cu in the former; T. Watanabe and I. Nakada, Jpn. J. Appl. Phys. JJAPA5 0021-4922 17, 1745 (1978).

32. After the original submission of this paper, Fichtl [R. Fichtl, Phys. Rev. Lett. PRLTAO 0031-9007 10.1103/PhysRevLett.94.027601 94, 027601 (2005)] reported "orbital glass" behavior in single crystalline Fe Cr2 S4, which shows Cp similar to our data on x=0.1. The intriguing behavior may be due to nonstoichiometry associated with the Cl-vapor growth method.

35. The uncertainty in the Δ value is from various fits with the upper T limit varied between 4-7 K. No systematic range dependence was observed. Tsurkan [cond-mat/0407026 (unpublished)], deduced an energy gap of 11.4 K from their low- T Cp data using a different function.
