Journal ArticleDOI

Direct evidence for anisotropic three-dimensional magnetic excitations in a hole-doped antiferromagnet

Rajesh Dutta, +7 more
- 15 Oct 2020 - 
TL;DR: In this paper, a neutron-scattering study was conducted on the magnetic spectrum of the half-doped region near the magnetic zone center, showing the presence of a sizable out-of-plane interaction resulting in an anisotropic three-dimensional nature of spin dynamics.
Journal ArticleDOI

Pseudogap and Superconducting Gap in Y-123: A Raman Study

Matthias Opel, +8 more
- 30 Jun 1999 - 
TL;DR: In this paper, an analysis of the data in terms of a memory function approach is presented and dynamical relaxation rates and mass-enhancement factors for the carriers are obtained, starting from temperatures T > 180K, and extrapolated to lower temperatures and used to re-calculate Raman spectra.

Raman scattering in solids

Matthias Opel, +1 more
TL;DR: Inelastic scattering of visible or ultraviolet light from matter is called "Raman scattering" after one of its discoverers as mentioned in this paper, which has become an important tool for the studies of elementary excitations in gases, liquids, and solids in the past years.
Journal ArticleDOI

Effect of substrate on the electrical transport property of Ba2FeNbO6 double perovskite thin films

N. Rama, +5 more
- 07 Mar 2007 - 
TL;DR: In this paper, the effect of substrate on the electrical transport of Ba2FeNbO6 (BFNO) under different growth conditions was studied and it was found that while the bulk and thin films grown on LaAlO3 and NdGaO3 substrates are insulating, the film grown on SrTiO3 substrate shows metallic behaviour.
Journal ArticleDOI

Surface distortion of Fe dot-decorated TiO2 nanotubular templates using time-of-flight grazing incidence small angle scattering

Neelima Paul, +7 more
- 04 Mar 2020 - 
TL;DR: In this article, magnetic nanodots of Fe on semiconductor TiO2 nanotubes (TNTs) are investigated with time-of-flight grazing incidence small-angle neutron scattering (TOF-GISANS) as a function of wavelength, chosen from a set of three TNT templates with different correlation lengths.
