OSTI ID:6844955
Neutron scattering experiments performed on single crystals of NdBa/sub 2/Cu/sub 3/O/sub 6.1/ reveal antiferromagnetic order for T < T/sub N/ = 385 +- 2K in which the structure is characterized by the magnetic wave vector (1/2 1/2 1/2). The magnetic intensities are accounted for the Cu/sup + +/ spins coupled antiferromagnetically in the CuO/sub 2/ planes. The oxygen deficient layers exhibit a small staggered magnetization epsilonS which induces the spin ordering /minus/S, /minus/epsilonS, /minus/S, +S, +epsilonS, +S, along the tetragonal axis. The average staggered magnetization evaluated at room temperature is about 0.40 ..mu..BETA in the CuO/sub 2/ planes and about 0.04 ..mu..BETA in the oxygen deficient layers. 8 refs., 2 figs., 1 tab.
