New NMR signals in antiferromagnetic YBa.Cu,O... with the N<:el temperature ofT.=4IO K have been observed in the frequency range between 65 MHz and 125 MHzat the zero external field. In corntrast to the nuclear quadrupole resonance (NQR) ob-served around 30 MHz, the newly observed signals are remarkably dominated by theappearance of the internal field generated by the antiferromagnetic ordering. Accord-ing to neutron diffraction studies, there exists an antiferromagnetic moment of about0.6 jt. on the Cub. plane site. Accordingly, NMR signals are unambiguously assignedto the Cub. plane site and NQR signals around 30 MHz to the CuO chain site. Thisfinding allows us to determine the magnetic phase diagram of YBa.Cu,O, , from amicroscopic point of view.[Cu-NMR, Cub. plane, antiferromagnetism, high-7'. superconductor, ll YBa.Cu.O...l
