Abstract
By measuring the beat frequency of the spin-echo amplitude modulation of pulsed Ba-137 NQR, the internal magnetic field of 14.8 mT perpendic ular to the tetragonal c-axis at the Ba site in the antiferromagnetic YBa2Cu3O6 at 80 K was determined. Calculation of the dipole field at t he Ba site due to localized antiferromagnetically ordered 0.66 mu(B) m agnetic moments at Cu(2) sites yields 47 mT.
