The magnetoresistive properties of La 0.7 Ca 0.3 MnO 3 change rapidly when Ti or Ga is substituted on the Mn site for concentrations, x, from 1 to 10%. The samples exhibit colossal magnetoresistance (CMR) and the resistivity increases dramatically wi

The electronic structure of Tl2Mn2O7 was examined by performing tight binding band calculations. The overlap between the Mnt2g- and Tl 6s-block bands results in a partial filling of the Tl 6s-block bands. The associated Fermi surface consists of 12 c

A series of zirconium and titanium phosphate sulfophenylphosphonates of the type M(HPO4)x(O3PC6H4SO3H)2 − x were prepared and characterized. They were found to exhibit proton conductivities which increased rapidly with increase in relative humidity

Analysis of the copper K-edge X-ray absorption finestructure on Tl2Ba2CuO6, Tl2Ba2CaCu2O8, and Tl2Ba1.2Sr0.8 CuO6 indicates that the copper-equatorial oxygen local structure changes in the vicinity of the superconducting transition. These data also s

On the basis of spin dimer analysis and density functional theory electronic band structure calculations, we examined why the magnetic ground state of SeCuO3 is ferromagnetic while that of its isostructural analogue TeCuO3 is antiferromagnetic and es

THE magnetic field penetration depth λ is a basic parameter of superconductivity, related to ns/m* (superconducting carrier density/effective mass) as λ-2 ∝ ns/m* in the limit where the coherence length ζ is much shorter than the mean free path
