Magnetism, superconductivity, and coupling in cuprate heterostructures probed by low-energy muon-spin rotation

• We present a low-energy muon-spin-rotation study of the magnetic and superconducting properties of YBa(2)Cu(3)O(7-delta)/PrBa(2)Cu(3)O(7-delta) trilayer and bilayer heterostructures. By determining the magnetic-field profiles throughout these structures, we show that a finite superfluid density can be induced in otherwise semiconducting PrBa(2)Cu(3)O(7-delta) layers when juxtaposed to YBa(2)Cu(3)O(7-delta) "electrodes," while the intrinsic antiferromagnetic order is unaffected.
