WebAug 4, 2024 · Here, we report transverse incommensurate spin density waves (SDWs) for the Mn atoms with a propagating direction along the chain axes as a ground state for KMn6Bi5 by single crystal neutron diffraction. WebApr 11, 2024 · Here we explore a series of metallic charge- and spin-density-wave systems that exhibit extremely large positive linear MR. By contrast to other linear MR mechanisms, this effect remains robust down to miniscule magnetic fields of tens of Oersted at low temperature. ...

WebFeb 17, 2006 · Recent ab initio calculations have shown that the theory of the spin density wave (SDW) based on the nesting property of the chromium Fermi surface is not able to explain solely the stability of the incommensurate SDW. Using the model Hamiltonian approach, we develop a method which allows self-consistent calculation of SDWs with … WebFeb 18, 2016 · The inverse of the spin-density and superconductivity correlation functions normalized to their value at ω 0 = 0.1 is shown in Fig. 2 for various values of α. The incommensurate and commensurate spin-density waves (Figs. 2(a) and 2(b)) are driven by the vertices v and p a, respectively. WebDec 31, 2014 · Here we propose that the incommensurate diagonal spin-density-wave order can account for the above experimental observation. The Fermi surface and the local density of states are also studied. Our results are in good agreement with many important experiments in high- superconductors. how to replace rv floor
