Rather complex Nuclear Quadrupole Resonance (NQR) spectrum of "'La inLazCuO. , observed at low temperatures is successfully interpreted as a signal from asingle La site which suffers a cornbined effect of a quadrupole coupling (coupling con-slant v.=6.38:0.02MHz with asymmetry parameter j=0.01f0.01) and a smallZeeman term where the internal field (H.= 0.997 8 0.010 k0e) is nearly perpendicularto the direction of the maximum field gradient. The spin strtacture of Cu at low temperatures is suggested to be a simple antiferromagnet wzith sublattice momentsparallel to the v-axis. The temperature dependences of v. and H. have been measuredin detail. The fractional decrease of H. which is proportional to the Cu sublatticemoments is found to be in general accord with the prediction of spin fluctuationstheory for weak itinerant antiferromagnets.
