Abstract We report high-resolution x-ray and neutron-scattering studies of the antiferromagnetism of the rare-earth superconductor, HoNi{sub 2}B{sub 2}C ({ital T}{sub {ital C}}=8.5 K). At low temperatures, {ital T}{lt}5 K, the superconductivity coexists with a long-range ordered, commensurate N{acute e}el state. In the incommensurate antiferromagnetic state, 5 K{lt}{ital T}{lt}7 K, we find two phase coexistence between an {ital a}-axis modulation and a {ital c}-axis basal plane spiral-like structure. The {ital c}-axis structure is characterized by two wave vectors. Short-range ordered fluctuations of the commensurate phase, observed for {ital T}{approx_gt}5 K, are interpreted in terms of local strains. {copyright} {ital 1996 The American Physical Society.}
