Magnetism and superconductivity in YBa2Cu3O6.41

We present transverse and zero field μSR results on a YBa2Cu3O6.41 polycrystal which show that the onset of magnetic order in a minority diluted volume fraction of our sample does not affect the muon relaxation of the majority superconducting volume fraction. The implications on the issue of coexistence of magnetism and superconductivity in high Tc cuprates is briefly discussed.
