摘要：
We have performed the elastic neutron scattering measurements under the uniaxial stress sigma for the antiferromagnetic (AF) state in CePd2Si2, and found an anisotropy in the sigma dependence of the AF state. The magnitude of the staggered moment is reduced with increasing sigma applied along the tetragonal [110] direction, while it shows nearly independent of sigma for sigma parallel to [001]. Similar behavior is also observed in the sigma dependence of the Neel temperature. From these results, we suggest that both the volume compression and the increase of the c/a ratio lead to the suppression of the AF state. (c) 2006 Elsevier B.V. All rights reserved.
