Influence of Nb, Mo, and Ti as doping metals on structure and magnetic response in NdFeB based melt spun ribbons
(Elsevier Science, 2018-09)
In this work, it is shown a comparative analysis of magnetic measurements that has been done over rapidly quenched melt-spinning alloyed ribbons with the formula NdyFe(86−y−x)B14Mx (X = 2, 4; Y = 7,8; M = Nb, Mo, Ti). The ...
Effects of Native Vacancies on Nb-Doped MgH 2 Using Density Functional Theory Calculations
(American Chemical Society, 2018-11-10)
In the present work, we considered the effect of Nb and charged vacancies on the properties of magnesium hydride. We performed spin-polarized ab initio calculations substituting an Mg atom by an Nb impurity. Then, some ...
Rietveld refinements of SnO(2) ceramic powders doped with ZnO, WO(3), CoO, Nb(2)O(5) and MoO(3)
(Oldenbourg Verlag, 2007-01-01)
Polycrystalline materials of SnO(2) doped with ZnO, WO(3), CoO, Nb(2)O(5), and MoO(3). were synthesized by solid state reaction. X-ray powder diffraction data were collected with Cu K(alpha) radiation from a Rigaku-Rint ...
