Superconductivity in Heavy Fermion Compounds
The heavy electron state in intermetallic lanthanide and actinide compounds has its origin in the interplay of strong Coulomb repulsion in the 4fand 5fshells and their hybridisation with conduction band states. Heavy quasiparticles have mostly been observed in Ceand U-based intermetallics which are therefore at the focus of this review. Ideally the ground state in these strongly correlated elec...
متن کاملTowards high-valent uranium compounds from metallacyclic uranium(IV) precursors.
Treatment of [NaUN*(C,N)(2)] [N* = N(SiMe(3))(2); C,N = CH(2)SiMe(2)N(SiMe(3))] with I(2) led to the formation of the larger metallacycle [UN*(N{SiMe(3)}SiMe(2)CH(2)CH(2)SiMe(2)N{SiMe(3)})I] resulting from U-C cleavage and C-C coupling. Reaction of [NaUN*(O,N)(2)] [O,N = OC(=CH(2))SiMe(2)N(SiMe(3))] with I(2) afforded the U(V) complex [Na{UN*(O,N)(2)}(2)(μ-I)] which was converted into the monon...
متن کاملMultiband superconductivity in BiS2-based layered compounds.
A mean-field treatment is presented of a square lattice two-orbital-model for [Formula: see text] taking into account intra- and inter-orbital superconductivity. A rich phase diagram involving both types of superconductivity is presented as a function of the ratio between the couplings of electrons in the same and different orbitals ([Formula: see text]) and electron doping x. With the help of ...
متن کاملSuperconductivity in anti-post-perovskite vanadium compounds
Superconductivity, which is a quantum state induced by spontaneous gauge symmetry breaking, frequently emerges in low-dimensional materials. Hence, low dimensionality has long been considered as necessary to achieve high superconducting transition temperatures (TC). The recently discovered post-perovskite (ppv) MgSiO3, which constitutes the Earth's lowermost mantle (D" layer), has attracted sig...
متن کاملMagneto-optic properties of uranium-based compounds
optic properties of uranium-based compounds" Uranium-based compounds often show interesting magnetic properties and large polar Kerr rotations. Because of this, the wavelength and temperature dependencies of the polar Kerr rotation in several uranium-based compounds, including UMnzGez, UFe2, and UGa2, have been investigated. The Mn moments order ferromagnetically in UMnzGel below 380 K, and whi...
