WebSpin-density wave. The ground state of a metal in which the conduction-electron-spin density has a sinusoidal variation in space, with a wavelength usually incommensurate with the crystal structure. This antiferromagnetic state normally occurs in metals, alloys, and compounds with a transition-metal component. 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 …
WebHere, we report a combined resonant soft X-ray scattering (RSXS) and neutron scattering study of charge and spin density waves in isotopically enriched La 1.8 − x Eu 0.2 Sr x CuO 4 over a range of doping 0.07 ≤ x ≤ 0.20. We find that the CDW amplitude is temperature independent and develops well above experimentally accessible temperatures. WebAbstract. Experimental searches were made for evidences for the charge- or spin-density wave state in the trigonal-prismatic pseudo-linear chain compound ZrTe5. Negative evidences for such phase transitions were provided by the absence of lattice modulation, ohmic resistivity at high electric fields, and by temperature and angular ...
Webdevices show great potential application for nano-scaled memory technology. Being possible in cross-bar architecture, the memory cell can be scaled to 4F2 dimensions, the best possible scaling so far in memory. Owning to superior bipolar resistive switching characteristic, the bipolar RRAM with WebThis review deals with the properties of superconductors with competing electron spectrum instabilities, namely, charge-density waves (CDWs) and spin-density waves (SDWs). The underlying reasons of the electron spectrum instability may be either Fermi surface nesting or the existence of Van Hove saddle points for lower dimensionalities.
