Abstract
In an investigation of the possible coexistence of superconductivity and magnetism, we have measured the Mössbauer effect of151Eu and119Sn in Eu z Sn 1−z Mo6S y (0≤z≤1,y≈7) between 0.05 and 4.2 K. The Eu spectra show a magnetic hyperfine splitting with a field of 27.3 T below 0.1 K; no fields in excess of 0.1 T have been observed at the Sn nuclei. For 0.1<T<0.5 K, the Eu Mössbauer spectra consist of a superposition of the static hyperfine spectrum observed forT≤0.1 K and a spectrum produced by electronic relaxation. In this intermediate temperature range the spectra can be understood as arising from ordered clusters in a paramagnetic surrounding, features we consider to be characteristic of a spin glass. The interaction between the Eu ions, and that between Eu ions and the “superconducting” Mod electrons, seem to be very weak.
