Heavy fermions in transition metals and transition-metal oxides [PDF]

The European Physical Journal B - Condensed Matter, 2003
Heavy-fermion formation in transition metals and transition-metal oxides is reviewed and compared to observations in canonical f-derived heavy-fermion systems. The work focuses on the dynamic susceptibilities which reveal a characteristic temperature and frequency dependence and which can be unambiguously determined via nuclear magnetic resonance and ...

Metal-insulator transition in transition metal oxides

Journal of Physics C: Solid State Physics, 1971
Electronic band structure calculations for TiO, VO, MnO, FeO, CoO, and NiO suggest that the 4s band becomes degenerate with the 3d band at VO and thus helps to destroy the Mott insulator state. The large difference in lattice constant between the metallic and insulating oxides is well accounted for in terms of the Mott transition.

Metal-insulator Transition in Transition Metal Oxides

IBM Journal of Research and Development, 1970
The metal-insulator transition in the V2O3 system is discussed. A recent series of experiments on V2O3 and (V1-xCrx)2O3 is reviewed. The phase diagram fort he system is described. The Cr-doped mixed oxides are insulating at room temperature for x ≥ 0.009 and transform to a metal with the application of pressure. This phase transition is identified as a

Semiconducting transition metal oxides

Journal of Physics: Condensed Matter, 2015
Open shell transition metal oxides are usually described as Mott or charge transfer insulators, which are often viewed as being disparate from semiconductors. Based on the premise that the presence of a correlated gap and semiconductivity are not mutually exclusive, this work reviews electronic structure calculations on the binary 3d oxides, so to ...

Half-metallic transition metal oxides

Journal of Magnetism and Magnetic Materials, 2004
Abstract We present an application of the self-interaction corrected local spin density approximation to study the electronic structure of half-metallic double perovskites Ba 2 FeMoO 6 , Ca 2 FeMoO 6 , Sr 2 FeMoO 6 , Ca 2 FeReO 6 , and charge order in Fe 3 O 4 .

Transition metal oxides

Choice Reviews Online, 1995
This chapter evaluates transition metal oxides, reviewing binary transition metal oxide structures. The structure of many binary oxides can be predicted on the basis of the relative sizes of the metal and oxide ions and filling of holes in a close peaked oxide lattice. Such predictions of structure are more difficult for ternary phases. The combination

Aromaticity in Transition Metal Oxide Structures

Journal of Chemical Information and Computer Sciences, 2001
The concept of aromaticity is useful for understanding the properties of some polyoxometalates containing transition metals such as vanadium, molybdenum, and tungsten having structures based on metal macropolygons and macropolyhedra with M-O-M edges.

The oxidation of toluene on transition metal oxides

Russian Journal of Physical Chemistry A, 2009
The oxidation of toluene on pure vanadium and molybdenum oxides was found to follow independent paths; it was benzene ring oxidation on V2O5 and side chain oxidation on MoO3. On mixed xV2O5 · yMoO3 oxides, the main reaction was the addition at the double bond preferably positioned meta rather than one-electron oxidation.

Monolayered Nanodots of Transition Metal Oxides

Journal of the American Chemical Society, 2013
Monolayered nanodots of titanium, tungsten, and manganese oxides were obtained by exfoliation of the nanocrystals through aqueous solution processes at room temperature. The precursor nanocrystals of the layered compounds, such as sodium titanate (Na(0.80)Ti(1.80)□(0.2)O4·xH2O, □: vacancy (x < 1.17)), cesium tungstate (Cs4W11O35·yH2O (y < 10.5)), and ...
