“…To date, spontaneous correlated magnetic Cu(2) moments have been evidenced in fully oxidised superconducting samples of YBa 2 Cu 3 O 7 substituted with both Ni (this work) and with Co or Fe 11,15 . Further information concerning the properties of magnetically correlated Cu(2) in Co substituted single crystals is given in the following paper 38 . Whereas each type of substitution (Ni or Co/Fe) lowers the superconducting transition temperature by approximately the same amount, each introduces quite different changes in some of the other properties.…”

We have examined the magnetic properties of polycrystalline, superconducting YBa2(Cu0.96Ni0.04)3Oy (y ∼7, Tsc ∼75 K) using two local probe techniques: 170 Yb Mössbauer down to 0.1 K and muon spin relaxation (µSR) down to 1.5 K. At 0.1 K, the 170 Yb measurements show the Cu(2) over essentially all the sample volume carry magnetically correlated moments which are static on the time-scale 10 −9 s. The moments show a distribution in size. The correlations are probably short range. As the temperature increases, the correlated moments are observed to fluctuate with measurable rates (in the GHz range) which increase as the temperature increases and which show a wide distribution. The µSR measurements also evidence that the fluctuation rates increase with increasing temperature and there is a distribution. The evidenced fluctuating, correlated Cu(2) moments coexist at an atomic level with superconductivity.
