Influence of the nonmagnetic impurities on the spin-1 Heisenberg chain SrNi2V2O8 system
(2006)De-magnetization and heat capacity measurements on polycrystalline samples of SrNi2-xMgxV2O8 (x = 0 and 0.05) are reported. The magnetization data suggest that both compounds are S= 1 quasi one-dimensional Heisenberg ...

Initial assessment of the thermoelectric properties for the mixed system K2-xRbxBi8Se13
(Affiliation: Dept. of Elec. and Comp. Engineering, Northwestern University, Evanston, IL 60208-3118, United StatesCorrespondence Address: Ireland, J.R.Dept. of Elec. and Comp. Engineering, Northwestern University, Evanston, IL 60208-3118, United States, 2002)In previous studies we have investigated the thermoelectric properties of undoped and doped compositions of β-K2Bi8Se13. The attempt to substitute Rb for K resulted in a different structure type, but with potentially useful ...

An inverse finite element method for directly formulated free boundary problems
(1989)In free boundary problems, in addition to the primary field variables, velocity, pressure and temperature, unknown geometric parameters need to be evaluated. A characteristic feature of the problems is a demarcation line ...
