Universal Temperature Behavior of Remanent Magnetization Observed in Low-Tc and High-Tc Josephson Junction Arrays
S. Sergeenkov, W. A. C. Passos, P. N. Lisboa-Filho +1
A comparative study of the magnetic remanence exhibited by tridimensional Josephson junction arrays in response to an excitation with an AC magnetic field is presented. The observe…
Unusual magnetic relaxation behavior in La0.5Ca0.5MnO3 and Nd0.5Sr0.5MnO3
J. Lopez, P. N. Lisboa-Filho, W. A. C. Passos +5
We have carried out a systematic magnetic relaxation study, measured after applying and switching off a 5 T magnetic field to polycrystalline samples of La0.5Ca0.5MnO3 and Nd0.5Sr0…
Magnetic field dependence of the critical current of tridimensional YBa2Cu3O7-x Josephson junction arrays
W. A. C. Passos, P. N. Lisboa-Filho, W. A. Ortiz
In this paper we determine the magnetic field dependence of the critical current of a tridimensional disordered Josephson junction array (3D-DJJA). A contactless configuration, emp…
Evaluating the critical current magnitude and distribution width of tridimensional Josephson junction arrays
W. A. C. Passos, U. R. de Oliveira, W. A. Ortiz
In this contribution we present a simple and effective procedure to determine the average critical current of a tridimensional disordered Josephson junction array (3D-DJJA). Using…
Magnetic relaxation and magnetization field dependence measurements in La0.5Ca0.5MnO3
J. Lopez, P. N. Lisboa-Filho, W. A. C. Passos +2
We reported a systematic change in the average magnetic relaxation rate, after the application and removal of a 5 T magnetic field, in a polycrystalline sample of La0.5Ca0.5MnO3. M…
Remanent magnetization of high-temperature Josephson junction arrays
W. A. C. Passos, P. N. Lisboa-Filho, W. A. Ortiz
In this work we study the remanent magnetization exhibited by tridimensional disordered high-Tc Josephson junction arrays excited by an AC magnetic field. The effect, as predicted…
