Magnetism, superconductivity, and coupling in cuprate heterostructures probed by low-energy muon-spin rotation
Abstract
We present a low-energy muon-spin-rotation study of the magnetic and superconducting properties of YBa2Cu3O7-δ/PrBa2Cu3O7-δ 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 PrBa2Cu3O7-δ layers when juxtaposed to YBa2Cu3O7-δ “electrodes,” while the intrinsic antiferromagnetic order is unaffected.
