Intrinsic magnetic properties of BixCo2-xMnO 4 spinels obtained by short-time etching
(2013-08-01)
We report the structural and magnetic properties of Co2MnO 4, partially substituted by Bi at the octahedral site. Bismuth enhances ferromagnetism due to a decrease of the Co2+-Co2+ antiferromagnetic interactions and an ...
The Spinel Explorer - Interactive Visual Analysis of Spinel Group Minerals
(Institute of Electrical and Electronics Engineers, 2014-12)
Geologists usually deal with rocks that are up to several thousand million years old. They try to reconstruct the tectonic settings where these rocks were formed and the history of events that affected them through the ...
Synthesis of Ca-doped spinel by ultrasonic spray pyrolysis
(ElsevierAmsterdam, 2016)
MgAl2O4 is a stable catalyst support with potential for replacing gamma-alumina in several applications. However, synthesis of magnesium spinel requires elevated temperatures to avoid phase separation (in MgO and Al2O3) ...
Characterization of nickel doped Zn7Sb2O12 spinel phase using Rietveld refinement
(J C P D S-int Centre Diffraction Data, 2003-09-01)
Zn7Sb2O12 is known to adopt an inverse spinel crystal structure, in which Zn2+ occupies the eight tetrahedral positions and Sb5+ and Zn2+ randomly occupy the 16 octahedral positions. Samples of Zn7-xNixSb2O12 (X = 0, 1, ...
Magnetic properties of spinel-type oxides NiMn2-xMexO4
(2005-09-01)
New materials, based on the well-known spinel compound NiMn 2O4, have been synthesized and characterized from the magnetic point of view. The manganese cation was partially substituted in the general formula NiMn2-xMexO4, ...

Determination of the spinel group end-members based on electron microprobe analyses
(Springer Wien, 2014-12-19)
The spinel group minerals have been the focus of many studies, not only because of their economic interest, but also due to the fact that they are very useful as petrogenetic indicators. The application End-Members Generator ...
