Satellite peak ratios according to stripes theory
نویسنده
چکیده
This paper looks at the expected results for a neutron diffraction study according to stripes theory, paying attention to the ratio of incommensurate to satellite peaks. In particular this paper looks at a square wave profile and the effects of doping on the peaks, for most doping levels seen in the literature (hole concentrations of 1/6 < p < 1/10) it appears that in order to detect satellite peak phenomenon a good lower bound for the signal-to-noise ratio is around 10. Finally information on the signal-to-noise ratio along with the domain wall spacing and doping from some recent neutron diffraction experiments is presented, this gives the reader an idea of whether any satellite peaks are observable at present. Using the signal-to-noise ratio and comparing to the peak ratio, none of the experiments which were found could make a conclusive claim on the existence of satellite peaks.

Magnetic excitations of stripes and checkerboards in the cuprates
We discuss the magnetic excitations of well-ordered stripe and checkerboard phases, including the high energy magnetic excitations of recent interest and possible connections to the “resonance peak” in cuprate superconductors. Using a suitably parametrized Heisenberg model and spin wave theory, we study a variety of magnetically ordered configurations, including vertical and diagonal siteand bo...

Abstract In this paper elastoplastic buckling of rectangular plates with different boundary conditions are investigated. Differential governing equations of plate are obtained on the basis of general loading and according to deformation theory (DT) of plasticity. Various loading conditions contain uniaxial, biaxial and shear are studied. The employed material is AL7075T6 which is usually used...
متن کاملThe evolution of surface flow stripes and stratigraphic folds within Kamb Ice Stream: why don’t they match?
Flow stripes seen in satellite imagery of ice streams and ice shelves are caused by surface undulations with kilometer-scale spacing and meter-scale relief and generally indicate current or recent fast ice flow. On a similar scale, folding of internal ice stratigraphy depicted in cross-flow icepenetrating radar profiles is also a common occurrence in ice streams, suggesting a possible relations...
متن کاملSexual dimorphism and morphometric study of Caspian pond turtle, Mauremyscaspica, (Testudines: Geoemydidae) in Golestan Province, southeast of the Caspian Sea
The Caspian pond turtle, Mauremyscaspica, is a terrapin belonging to family Geoemydidae. Totally 130 specimens (67 males and 63 females) were collected manually and by net from different aquatic habitats in Golestan Province from 2016 through 2017. Morphometric characteristics such as length were measured using digital caliper and weight by electronic weighting scale. Skin of this turtle was da...
متن کاملEvidence for gamma-ray bursts originating within 11 Mpc
We investigate the number of gamma-ray bursts in two particular strips of the sky using the data in 3B catalog of Burst and Transient Source Experiment (BATSE). One stripe is related to the plane in which the intergalactic globular clusters (R > 25kpc) and Galactic satellite galaxies (45kpc< R < 280kpc) concentrate, the other is concerned to nearby galaxies (1Mpc< R < 11Mpc). We find that the d...
