Abstract
Muon spin rotation experiments performed on a series of La2-xCa1+xCu2O6 (x = 0.12, 0.16, 0.22) superconductors indicate the existence of the magnetic correlations in the superconducting phase below T similar to 6 K. The incre ase in sample inhomogeneity strengthens these correlations. For the superco nducting phase, the extrapolated sigma(0) values fulfill the universal Uemu ra relation between T-c and sigma(0).
