Low temperature structural distortion in the high Tsub(c) chevrel-phase superconductors PbMo6S8 and SnMo6S8
Description
High-resolution powder neutron diffraction data reveal that, at temperatures below 100 K, oxygen-free, high-Tsub(c) samples of PbMo6S8 and SnMo6S8 exhibit a small structural distortion from the R3 rhombohedral space group. The data cannot be refined in a simple P1 triclinic space group as previously reported for EuMo6S8 and BaMo6S8. Thus, a supercell ordering is suggested. (author)
