Abstract [en]

We show, by means of low-energy muon-spin-rotation measurements, that few-unit-cells thick La2CuO4 layers synthesized digitally by molecular beam epitaxy are antiferromagnetically ordered. Below a thickness of about 5 CuO2 layers the long-range ordered state breaks down, and a magnetic state appears with enhanced quantum fluctuations and a reduced spin stiffness. This magnetic state can exist in close proximity (few Å) to high-temperature superconducting layers, without transmitting supercurrents. Charge-transfer effects and potential softening of the antiferromagnetic state due to the proximity to the superconducting state are discussed.
