Muon and hydrogen bonding, and magnetic resonance in pure and doped 519-01519-01519-01
Abstract
Results of three magnetic resonance studies on pure and doped YBa2Cu3O7 (Y1237) are compared. The muon and the proton, in low concentrations, behave similarly in these cuprates; both magnetic probes bond to oxygens just below the BaO planes. Phase changes from superconducting to magnetic behavior of H-doped Y1237 correspond to similar transitions observed for either 0 depletion or (Pr,Y) mixing. Chemical phase-separation effects are unlikely to be responsible for the simultaneous observation of superconductivity and magnetism. The similarity of the physical effects caused by H doping, O depletion, or (Pr, Y) mixing in the 1/2/3 cuprates points toward a plausible magnetic origin of CuO-based superconductivity.
