Fabrication of fibers with high rare-earth concentrations for Faraday isolator applications
John Ballato,Elias Snitzer +1 more
TL;DR: The novel powder-intube method, or a single-draw rod-in-tube method, was used to make silica-clad optical fibers with a high terbium oxide content aluminosilicate core, which could lead to all-fiber isolators of dramatically lower cost and ease of fabrication compared with their crystalline competitors.

Raman characterisation of powder of cubic RE2O3 (RE = Nd, Gd, Dy, Tm, and Lu), Sc2O3 and Y2O3
TL;DR: In this paper, the Raman spectra of cubic rare earth oxides are presented and the position of the low wave number bands depends mainly on the cationic mass, meaning that these bands are not due to stretching vibrations, but rather to bending vibrations.
Journal ArticleDOI
Raman spectra of R2O3 (R—rare earth) sesquioxides with C-type bixbyite crystal structure: A comparative study
TL;DR: In this article, the frequency of the six lowest frequency peaks scales with the square root of the mass of the rare earth showing that mainly R ions take part in these vibrations, and the anomalous softening of some peaks in the spectra of Eu2O3 is discussed.

A Raman spectroscopic study of C-type rare earth sesquioxides
Nita Dilawar,Shalini Mehrotra,Deepak Varandani,B.V. Kumaraswamy,S.K. Haldar,Abhijit Bandyopadhyay +5 more
TL;DR: In this article, Raman spectroscopy was used to study the variation in vibrational spectra of a series of rare earth sesquioxides of composition Ln2O3 (where Ln = Y, Sm, Eu, Gd, Dy, Ho, Er and Yb).

Design of Oxygen Vacancy Configuration for Memristive Systems
TL;DR: In this article, the role of oxygen vacancies either set as free or as immobile and clustered for resistive switching performance was investigated for oxide-based valence-change memristors.

Infrared absorption study of metal oxides in the low frequency region (700-240 cm−1)
Neil T. McDevitt,William L. Baun +1 more
TL;DR: In this article, the characteristic frequencies of 52 metals have been studied in the region 700-240 cm−1 and a particle size of 10 μ or smaller was found to give the best representative spectrum.

Study by Raman spectroscopy of order‐disorder phenomena occurring in some binary oxides with fluorite‐related structures
TL;DR: In this paper, order-disorder phenomena in binary oxides with fluorite-related structures were studied by Raman spectroscopy, showing broad bands, defects leading to selection rule breakdown.

Linus Pauling,M. D. Shappell +1 more
TL;DR: An atomic arrangement based on the space group T^5 was assigned this C-modification of the sesquioxides by Zachariasen as discussed by the authors, who studied crystals of Sc 2O_3, Mn 2O-3, Y 2O -3, In 2O −3, Tl 2O 3, Sm 2O+3, Eu 2O−3, Gd 2O&3, Dy 2O3, Ho 2O•3, Er 2O´3, Lu 2O'3, and the mineral bixbyite
