OSTI ID:4426177
From 19th conference on magnetism and magnetic materials; Boston, Massachusetts, USA (13 Nov 1973). The ORNL neutron camera is used to study structures in two Cr crystals. One crystal cut from an arc melted ingot showed two large domains that differ in the ddrection of the wave vector of the transverse linear spin density wave. The spatial variation of the mean polarization direction was analyzed for one of these domains and found to vary continuously across the crystal. Presumably the mean direction follows the local strain field. The other crystal grown from vapor, and presumably rather less influenced by strain effects, shows that the two components of the polarization coexist over most of the specimen in regions small compared to the resolution of the experiment,~ 0.5 mm.
