Abstract
Resonant and nonresonant x-ray magnetic scattering techniques have been used to study the low-temperature magnetic structure of GdNi2B2C. Taken together, these measurements allow a determination of the ordered moment direction and its evolution with temperature from a single orientation of the sample. The experimental results show that below approximately 19.4 K this compound forms an incommensurate antiferromagnetic state with a magnetic wave vector of approximately 0.55a(star) (b(star)) in the basal plane of the tetragonal structure. Between 19.4 and 13.6 K, the ordered moment is along the b (a) axis. Below approximately 13.6 K an ordered component of the moment develops along the c axis.
