A strong correlation between field-induced antiferromagnetic (AF) order and superconductivity is demonstrated for an electron-doped cuprate superconductor, Pr 1-xLaCe xCuO 4-δ (PLCCO). In addition to the specimen with x = 0.11 (which is close to the AF phase boundary, x ≃ 0.10), we show that the specimen with x = 0.15 (T c ≃ 16 K at zero field) also exhibits the field-induced AF order with a reduced magnitude of the induced moment. The uniform muon Knight shift at a low magnetic field (∼ 10 2 Oe) indicates that the AF order is not localized within the cores of flux lines, which is in marked contrast to theoretical predictions for hole-doped cuprates. The presence of anomalous nondiagonal hyperfine coupling between muons and Pr ions is also demonstrated in detail.
