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…
Magneto - transport characterization of Dy123 monodomain superconductors
M. Pekala, J. Mucha, Ph. Vanderbemden +2
The following report considers textured materials of the DyBa2Cu3O7 type seeded with a Nd123 seed as initiator. They are grown with an excess 20% Dy211 phase on a Dy2O3 substrate.…
Analysis of Experimental Conditions for Simultaneous Measurements of Transport and Magnetotransport Coefficients of High Temperature Superconductors
J. Mucha, S. Dorbolo, H. Bougrine +2
Experimental conditions for simultaneous measurements of transport coefficients of high temperature superconductors in zero and non-zero magnetic fields are analysed. Test measurem…
Thermal conductivity of solid parahydrogen with methane admixtures
A. I. Krivchikov, V. V. Sumarokov, J. Mucha +3
The thermal conductivity of solid parahydrogen crystal with methane admixtures has been measured in the temperature range 1.5 to 8 K. Solid samples were grown from the gas mixture…
