| Abstract: | The positive muon spin relaxation method is applied to probe magnetic ordering in the superconducting phase of a high quality single crystal of La2−xSrxCuO4−σ (0.11≤x≤0.14). The well characterized crystal ofx=0.11 (T c=34.5 K) with nearly complete flux exclusion exhibits spin freezing at 8K(T f) with significant spin fluctuation up to 20 K. The onset of spin fluctuation andT f decrease against increasingx towardsx=0.15, suggesting an existence of a magnetic phase boundary aroundx whereT c becomes maximum. |
