Abstract

Mössbauer Spectroscopy studies with ¹¹⁹Sn substituted for Cu in GdBa₂(Cu_0.99Sn_0.01)₃O₇ (T_c = 90 K) reveal the occurrence of a transferred hyperfine interaction at temperatures below 60 K. The effective magnetic field is 8.3 KOe at 57 K and decreases gradually with decreasing temperature to 6 KOeat 16 K. The onset of the magnetic interaction at the non-paramagnetic ¹¹⁹Sn probe is explained in terms of local depletion of holes due to the Sn⁴⁺ doping, consequently quenching the magnetic fluctuations around the impurity. These experimental findings provide strong evidence for spin-spin correlations originating from the Cu²⁺ moments and present in the superconducting state.
