Magnetocaloric effect in nano- and polycrystalline manganite
M. Pekala, V. Drozd, J. F. Fagnard +2
samples were prepared in nano- and polycrystalline forms by sol-gel and solid state reaction methods, respectively, and structurally characterized by synchr…
Influence of Zeeman splitting and thermally excited polaron states on magneto-electrical and magneto-thermal properties of magnetoresistive polycrystalline manganite La_{0.8}Sr_{0.2}MnO_3
S. Sergeenkov, J. Mucha, M. Pekala +2
Some possible connection between spin and charge degrees of freedom in magneto-resistive manganites is investigated through a thorough experimental study of the magnetic (AC suscep…
Effect of Ga doping on magnetotransport properties in collosal magnetoresistive La0.7Ca0.3Mn1-xGaxO3 (0 < x < 0.1)
Marek Pekala, Jan Mucha, Benedicte Vertruyen +2
Samples of La0.7Ca0.3Mn1-xGaxO3 with x = 0, 0.025, 0.05 and 0.10 were prepared by standard solid-state reaction. They were first characterized chemically, including the microstruct…
Unusual thermoelectric behavior of packed crystalline granular metals
M. Ausloos, M. Pekala, J. Latuch +4
Loosely packed granular materials are intensively studied nowadays. Electrical and thermal transport properties should reflect the granular structure as well as intrinsic propertie…
Hidden Superconductivity in Solid Solutions Sr(1-x)La(x)PbO3 detected by tunneling
V. A. Drozd, T. Ekino, A. M. Gabovich +2
Solid solutions of Sr1-xLaxPbO3 (x = 0, 0.05, 0.10, 0.15 and 0.20) were synthesized with the help of high pressure. Temperature (T) dependences of the resistivity r and differentia…
Heat capacity of mesoscopically disordered superconductors:implications to MgB
A. M. Gabovich, A. I. Voitenko, Mai Suan Li +2
Electronic heat capacity was calculated for a mesoscopically disordered s-wave superconductor treated as a spatial ensemble of domains with a continuously varying superconducting p…
