Magnetic properties of magnetically textured Bi-2212 ceramics
Ph. Vanderbemden, H. Bougrine, M. Ausloos +1
This paper aims at reporting magnetic properties of bulk polycrystalline Bi2Sr2Ca0.8Dy0.2Cu2O8-y samples textured under a magnetic field. The microstructure of these materials is h…
Anomalous temperature behavior of resistivity in lightly doped manganites around a metal-insulator phase transition
S. Sergeenkov, M. Ausloos, H. Bougrine +2
An unusual temperature and concentration behavior of resistivity in has been observed at slight doping (). Namely, introdu…
Influence of Cu on spin-polaron tunneling in the ferromagnetic state of La(2/3)Ca(1/3)Mn(1-x)Cu(x)O(3) from the resistivity data
S. Sergeenkov, H. Bougrine, M. Ausloos +1
Nearly a 50% decrease of resistivity ρ(T,x) due to just 4% Cu doping on the Mn site of La(2/3)Ca(1/3)Mn(1-x)Cu(x)O(3) is observed. Attributing the observed phenomenon to the substi…
Negative magnetoresistance in La(0.6)Y(0.1)Ca(0.3)MnO(3): Evidence for charge localization governed by the Curie-Weiss law
S. Sergeenkov, H. Bougrine, M. Ausloos +1
Colossal negative magnetoresistance Δρ(T,B) observed in La(0.6)Y(0.1)Ca(0.3)MnO(3) at B=1T shows a nearly perfect symmetry around T_0=160K suggesting a universal field-induced tran…
Estimation of the charge carrier localization length from Gaussian fluctuations in the magneto-thermopower of La_{0.6}Y_{0.1}Ca_{0.3}MnO_3
S. Sergeenkov, H. Bougrine, M. Ausloos +1
The magneto-thermoelectric power (TEP) of perovskite type manganise oxide is found to exhibit a sharp peak at some temperature …
