Ti-sheathed MgB2 wires doped with different amount of nanosized rare-earth oxide (Yb2O3, Gd2O3, and Dy2O3) and/or nanosized SiC were investigated. X-ray diffraction patterns suggested the existence of Mg2Si phase due to the SiC addition, while no any phase related to rare-earth oxide could be detected. Strong enhancement of in-field current carrying capability was observed on 2.5 wt.% Yb2O3 dop...

The development of a recycling process for rare-earth-containing waste is important improving the resource conservation and security rare-earth metals. Phase equilibria between molten fluoride oxide were investigated to develop novel neodymium magnets based on flux-remelting method. LiF—rare-earth (REF3, RE = Nd, Dy) mixtures oxides (RE2O3, selected, phase in Nd2O3−NdF3−Li2O−LiF Dy2O3−DyF3−Li2O...

This paper presents preliminary results of Dy2(CO3)3→Dy2O3 transition have been successfully obtained by Chemical Bath Deposition technical and subsequent thermal annealing temperature at ~600 °C. Two different temperatures ~20°C ~90 °C ± 2 are chosen to carry out the nanocrystalline growth. The crystalline phase is investigated applying X-Ray Diffraction (XRD) some optical properties; Transmit...

Developments in the field of glass research necessitate mimicking optical properties materials before melting raw materials, as they are very expensive nowadays. An artificial neural network (ANN) was utilized during this work to train and predict Judd–Ofelt parameters various glasses, such ?2, ?4 ?6, radiative lifetimes many different types rare-earth-doped glasses. The optimized ANN architect...

A new series of lithium-borate glass systems (23Li2O-72B2O3 in mol%) were synthesized with the substitution Al2O3 (5 mol.%) as a modifier and doped 0.3 0.5 mol% Dy2O3. Four glasses (S1, S2, S3 S4) via conventional melt-quenching technique characterized by using UV-Visible-NIR absorption spectrometer Fourier transform infrared (FTIR) spectroscopy. The current investigation gives further insight ...

The ac susceptibility and magnetization curves of a glued Dy(2)O(3) powder sample are measured by an ac susceptometer and a dc superconducting quantum interference device magnetometer, both of which have been calibrated previously. It is shown that the magnetic moment of the paramagnetic sample as a function of field and temperature may be accurately expressed by a combination of the Curie-Weis...
