A.C. susceptibility and magnetisation measurements on polysulphur nitride, (SN)_x

Measurements of the complex A.C. susceptibility and magnetization of crystals of polysulphur nitride, (SN)x, are reported. At temperatures near 0.2K both the in-phase and quadrature components of the A.C. susceptibility show a marked change which can be related to the onset of superconductivity. However, changes in the sample magnetization could not be detected. © 1977.
