Query: 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 YBa2Cu3O7/PrBa2Cu3O7 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 layers when juxtaposed to YBa2Cu3O7 "electrodes"
while the intrinsic antiferromagnetic order is unaffected.
