Nuclear Spin-lattice Relaxation in Metallic Ferro- and Antiferromagnets
The nuclear spin-lattice relaxation rates 1 / T I were found to be independent of temperature in the paramagnetic states of various kinds of metallic magnets. It has been ascertained from quantitative analyses that the values of 1 / Ti in the weak itenerant ferromagnets and the localized moment systems were explained by the SCR and the HBEN theories of spin fluctuations, respectively. Both theo...
متن کاملFamilies of Molecular Hexa- and Trideca-Metallic Vanadium(III) Phosphonates
The synthesis and structural characterization of two families of low-valent vanadium(III) {V6P4} and vanadium(III/IV) {V13P8} phosphonate complexes are reported. Magnetic characterization is reported for representative examples.
متن کاملOrganometallic benzene-vanadium wire: A one-dimensional half-metallic ferromagnet.
Using density functional theory we perform theoretical investigations of the electronic properties of a freestanding one-dimensional organometallic vanadium-benzene wire. This system represents the limiting case of multidecker Vn(C6H6)(n+1) clusters which can be synthesized with established methods. We predict that the ground state of the wire is a 100% spin-polarized ferromagnet (half-metal). ...
متن کاملAnomalously low electronic thermal conductivity in metallic vanadium dioxide.
In electrically conductive solids, the Wiedemann-Franz law requires the electronic contribution to thermal conductivity to be proportional to electrical conductivity. Violations of the Wiedemann-Franz law are typically an indication of unconventional quasiparticle dynamics, such as inelastic scattering, or hydrodynamic collective motion of charge carriers, typically pronounced only at cryogenic...
متن کاملMicrobial Demetallization of Crude Oil Using Aspergillus sp.: Vanadium Oxide Octaethyl Porphyrin (VOOEP) as a Model of Metallic Petroporphyrins
An isolate from polluted soil identified as Aspergillus sp. MS-100 was able to consume vanadium oxide octaethyl porphyrin as a model for protoporphyrins in crude oil. The isolate degrades about 55% of vanadium oxide octaethyl porphyrin (VOOEP) under optimum conditions during 7 days. The release of more than 0.96 mgl-1 of free vanadium into the aqueous phase was confirmed using atomic absorption...
