Abstract

Abstract Neutron diffraction experiments, performed on a powder sample, have shown that the reduced compound YBa 2Cu 3O 6 orders with an antiferromagnetic structure at a temperature as high as 500 K. Magnetic moments of about 0.48±0.05 μ B are aligned along the tetragonal c-axis and exhibit an antiferromagnetic coupling both in the basal plane ( k 0=[ 1 2 1 2 0] ) and in between the two CuO 2 layers of the unit cell. A discussion of the results is presented.
