Abstract
We performed zero and transverse field muon spin rotation experiments on a large number of samples. We detect the coexistence of antiferromagnetic (AF) short range magnetism with superconductivity below in compositions . Most muons experience local AF fields, even when a SQUID detects a full superconducting volume fraction, which points to a local minimal interference organization of short AF stripes embedded in the superconductor. A detailed phase diagram is produced and the consequences of the minimal interference are discussed.
