Transition-metal rich micas offer interesting properties with regard to magnetism and electric conductivity and moreover allow for a post-synthesis modification of the layer charge by oxidation which makes them interesting for a variety of applications. In this line, a Co and F-rich Cs-mica analog...
The peroxides of transition metals either in complexes or in high oxidation states (or in both), however, contain peroxide linked to the metal by directed bonds, and are closely related to the oxygenated O 2 -carrying complexes. The characteristic and interesting properties of transition metal ...
The metal-oxygen (MO6) octahedron, which is the essential structure building unit of these materials, exhibits a characteristic out-of-centre distortion for the d0 configuration in many instances, the degree of distortion increasing with decreasing HOMO-LUMO gap. Several characteristic properties of ...
(24) cluster are significantly changed by the dopant , inducing a characteristic absorption peak in the IR spectra of all the M@Au(24), and (3) protected by the tubular Au(24), the 3d states of the dopant are largely localized, and the atom-like magnetism is retained for all the ...
The theory of dilute magnetic alloys with 4d and 5d transition metals as host is reviewed. The close relationship between the Wolff and Anderson models permits a unified interpretation of the single impurity properties of dilute alloys with noble and transition metals as host. We show that some ...
The LDA+DMFT description captures the physics correctly: the titanates are Mott insulators while the vanadium compounds are correlated metals with a characteristic three-peak structure (see Fig. 2) consisting of upper and lower Hubbard bands and a quasiparticle peak. This correlated metal behavior ...
For instance, compounds such as KMCl3 (M = Ir, Rh), KCrX3 (X = Cl, Br, I), RbCrX3 (X = F , Cl, Br, I), and CsRhCl3 exhibit half-metallicity, with transition metals like Cr, Rh, and Ir playing a crucial role in their conducting properties25,26,27,28. Remarkably, the A...
1. What are the characteristic electron configurations of transition metals? (Electron configurations have partially filled nd sub-shell) 2. What is the general trend in atomic size across a transition metal series? (Atomic size initially decreases, reach minimum near the middle, and slightly increa...
