fA strong correlation between field-induced antiferromagnetic (AF) order and superconductivity is demonstrated for an electron-doped cuprate superconductor, Pr1-xLaCexCuO4-delta (PLCCO). In addition to the specimen with x = 0.11 (which is close to the AF phase boundary, x similar or equal to 0.10), we show that the specimen with x = 0.15 (T-c similar or equal to 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 (similar to 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.
