The thermodynamic stability and hydration enthalpy of strontium cerate doped by yttrium
N. I. Matskevich, Th. Wolf, M. Yu. Matskevich
The standard molar enthalpy of formation of SrY0.05Ce0.95O2.975 has been derived by combining the enthalpy of solution of this compound in 1 M HCl + 0.1 KI obtained by us and auxil…
Decomposition of solid solutions in the Nd-Ba-Cu-O system and its influence on changing transport characteristics
N. I. Matskevich, O. I. Anyfrieva, T. D. Karpova +3
Thermochemical characteristics of Nd1+xBa2-xCu3Oy solid solutions were studied by solution calorimetry. Dependences of formation enthalpies from Nd content were constructed. It was…
Study of the SmBaCuO solid solutions decomposition and its possible role for changing critical current
N. I. Matskevich, A. I. Romanenko, L. V. Yakovkina +2
We studied thermochemical characteristics of the Sm1+xBa2-xCu3Oy single crystals by solution calorimetry. Dependences of formation enthalpies from samarium content were constructed…
Electronic structure of single-crystalline Mg(x)Al(1-x)B(2)
S. Schuppler, E. Pellegrin, N. Nuecker +11
Polarization-dependent x-ray absorption spectroscopy at the B 1s edge of single-crystalline Mg(x)Al(1-x)B(2) reveals a strongly anisotropic electronic structure near the Fermi ener…
Calorimetric Investigation of NdBa2Cu3Ox Single Crystals
U. Tutsch, P. Schweiss, R. Hauff +3
The specific heat of Nd(Y)Ba2Cu3Ox single crystals without substitution of Nd for Ba has been measured for various oxygen contents. In comparison with YBa2Cu3Ox, the maximum attain…
In-Plane and Out-of-Plane Optical Properties of NdBa2Cu3Ox Single Crystals close to x = 7.0
R. Hauff, M. Goeppert, B. Obst +3
We present results of reflectivity measurements with E parallel to c and E perpendicular to c on NdBa2Cu3Ox (Nd123) single crystals close to full oxygen doping. Along the c-axis th…
