WebMar 27, 2024 · Introduction. Incommensurate spin-density wave (ISDW) phases have long been known to be generated from paramagnetic (PM) metals either through a Fermi … WebFor a sample with x~9(1)%, we also find an incommensurate spin-density wave that competes with the bicollinear commensurate ordering close to …

“Nodal Gap” Induced by the Incommensurate Diagonal Spin Density …

Webresolved incommensurate orders of the CDW in NbSe 2 and the SDW in Cr, we examine the fundamental physics of density wave formation approaching a pressure-driven critical point. We find that an itinerant electron instability plays a dominant role when the order parameter forms, taking on a pure sinusoidal shape 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 … hacin boston
