Abstract
We report on EPR experiments on single crystals of La2-xSrxCuO4+delta for Sr-concentrations 0.07 less than or equal to x less than or equal to 0.20. Intrinsic EPR signals have been observed for all concentratio ns. The anomalous temperature dependence of the g-shift and of the lin e width are explained in terms of a strong coupling of the EPR probe t o the spin fluctuations in the CuO2 planes.
