Phys. Rev. Lett. 85, 3500–3503 (2000)Observation of Charge-Density Wave Domains on the Cr(110) Surface by Low-Temperature Scanning Tunneling MicroscopyReceived 11 April 2000; published in the issue dated 16 October 2000 We have studied the Cr(110) surface with low-temperature scanning tunneling microscopy at 6 to 145 K. For tunneling voltages below ±150 mV we observe a surface charge-density wave (CDW) with a wavelength of 42 Å and wave fronts aligned with the [001] in-plane direction. The observed wave pattern is identified as the surface projection of the bulk CDW's arising from the spin-density wave ground state of Cr with the Q vector parallel to [100] and [010], respectively. The bulk CDW with Q parallel to the [001] in-plane direction appears, however, to be strongly suppressed at the Cr(110) surface. © 2000 The American Physical Society URL:
