The local magnetic susceptibility wloc around a positive muon in quasi-one-dimensional spin 1/2 antiferromagnetic chain compounds dichlorobis KCuF3 has been investigated using muon spin rotation/relaxation muSR: We compare chi_loc with the bulk magnetic susceptibility chi measured in a SQUID magnetometer. In all cases there is a dramatic difference between chi_loc and chi; as predicted by theory.
