Metallic Surface Reconstruction Driven by Frustrated Antiferromagnetism
A magnetic origin for the honeycomb reconstruction of metallic surfaces with three-fold symmetry like Pb/Ge (111) is proposed. Assuming that the groundstate is an antiferromagnet insulator over the triangular lattice of adatom sites (Pb), we demonstrate that the former is simultaneously unstable to canting and to a structural distortion if the surface is soft enough. We therefore predict a net ...
متن کاملMagnetism of frustrated metallic compound BaVS3
The microscopic magnetism of BaVS3, which undergoes a metal-insulator transition at TMI = 70K, has been investigated by using V nuclear resonance and neutron scattering. At 1.4K, we observed zero-field resonance signals in a low-frequency range, which were interpreted as being NQR, i.e., the absence of a static hyperfine field. On the other hand, we found magnetic Bragg peaks below 30K, indicat...
متن کاملAnomalous Magnetothermopower in a Metallic Frustrated Antiferromagnet.
We report the temperature T and magnetic field H dependence of the thermopower S of an itinerant triangular antiferromagnet PdCrO_{2} in high magnetic fields up to 32 T. In the paramagnetic phase, the zero-field thermopower is positive with a value typical of good metals with a high carrier density. In marked contrast to typical metals, however, S decreases rapidly with increasing magnetic fiel...
متن کاملOn surface reconstruction: A priority driven approach
To reconstruct an object surface from a set of surface points, a fast, practical, and efficient priority driven algorithm is presented. The key idea of the method is to consider the shape changes of an object at the boundary of the mesh growing area and to create a priority queue to the advanced front of the mesh area according to the changes. The mesh growing process is then driven by the prio...
متن کاملSurface Driven Bulk Reconstruction of Gold Nanorods
The properties of metallic clusters of various shapes, on the nanometer length scale, can be dramatically different from the corresponding bulk material due to their very large surface-to-volume ratio. The unique optical and mechanical properties of such nanoclusters hold great promise for the development of nanotechnology. Gold nanoclusters, for example, have found application in such diverse ...
