Incommensurate spin crystal
WebApr 20, 2024 · The researchers at the University of Warwick, UK, say the object they call an “incommensurate spin crystal” resembles a skyrmion hidden in an ultrathin film with ferroelectric and ferromagnetic layers, and could be used to make storage bits for next-generation computer memories. Skyrmions exist in many structures, notably magnetic … WebApr 14, 2024 · Charge and spin density waves are typical symmetry broken states of quasi one-dimensional electronic systems. They demonstrate such common features of all incommensurate electronic crystals as a spectacular non-linear conduction by means of the collective sliding and susceptibility to the electric field. These phenomena ultimately …

WebFeb 25, 2011 · Na, 75. As-NMR Experiments. We report the results of 23 Na and 75 As nuclear magnetic resonance (NMR) experiments on a self-flux grown high-quality single crystal of stoichiometric NaFeAs. The NMR spectra reveal a tetragonal to twinned-orthorhombic structural phase transition at T O = 57 K and an antiferromagnetic (AF) … WebThe Fourier module of the n -dim lattice is a periodic reciprocal n-dim lattice with sharp diffraction spots. This is the space in which inelastic scattering experiments are done to investigate the atomic dynamics. For incommensurate crystals, the 3D reciprocal space can be constructed on the basis of three reciprocal basis vectors.

An incommensurate magnetic structure is a structure in which the magnetic moments are ordered, but without periodicity that is commensurate with that of the nuclear structure of the crystal. In particular, the magnetic moments have a spin density with wave vectors that have at least one irrational …
