Antiferromagnetism of La/sub 2/CuO/sub 4-//sub y/ studied by muon-spin rotation
Journal Article

· Phys. Rev. Lett.; (United States)
Zero-field spin precession of positive muons has been observed in the antiferromagnetic state of La/sub 2/CuO/sub 4-//sub y/. Sharp onsets of the sublattice magnetization are found at temperatures close to those of the susceptibility maxima of different specimens. The long-lived precession signal indicates a microscopically homogeneous distribution of spin density at each Cu atom below the Neel temperature. Combination of the present results and neutron-scattering studies indicates the ordered moment per Cu atom to be significantly less than 1..mu../sub B/.
