Relationships between structure and physical properties in SmNi(1-x)Co(x)O3
(Academic Press Inc Elsevier Science, 2000-03)
The crystal structure of SmNi(1-x)Co(x)O3 perovskites, with 0 ≤ x ≤ 1, has been determined at room temperature by Rietveld analysis from X-ray powder diffraction data. Polycrystalline samples have been prepared using high ...
Lattice effects in the quasi-two-dimensional valence-bond-solid Mott insulator EtMe3P[Pd(dmit)(2)](2)
(Amer Physical Soc, 2014)
Phase Transition and Spatial Correlation of Localized States in the Falicov‐Ramírez‐Kimball Model
(1981)
The Falicov‐Ramirez‐Kimball model is solved by means of the two‐atom cluster Caron‐Pratt approximation. Metallic and insulating phases according to the value of an order parameter Δ are obtained, and both second‐ and ...
Lattice effects in the quasi-two-dimensional valence-bond-solid Mott insulator EtMe 3 P[Pd(dmit) 2] 2
(2014-01-10)
The organic charge-transfer salt EtMe3P[Pd(dmit)2]2 is a quasi-two-dimensional Mott insulator with localized spins S=1/2 residing on a distorted triangular lattice. Here we report measurements of the uniaxial thermal ...
Electronic phase transitions of cerium metal
(1972)
The model recently proposed by Ramírez and Falicov is generalized by the incorporation of the spin-orbit splitting of the 4f shell. This generalization provides an understanding of the fractional valence and magnetic ...
