|Abstract:||Incommensurate spin-density wave (SDW) in chromium presents Q-domain configurations that can be studied through X-ray diffraction (XRD) due to charge-density wave satellites at (0 0 1) and (1 1 1) crystal faces. In the present work, we investigated superficial domains reorientation in the bulk multi-Q state, after the crystal had been maintained in the bulk single-Q state artificially prepared by field cooling under 90 kOe applied in (0 1 0)direction. Reciprocal lattice scans were performed along the three directions H, K and L to ensure proper CDW satellite measurements. Our results are in agreement with previous experiments where observed that the preferential orientation of CDW occurs naturally with Q perpendicular to the surface, parallel to (1 0 0). © 2006 Elsevier B.V.
