Anomalous metamagnetic-like transition in a FeRh/FePt interface occurring at T120 K in the field-cooled-cooling curves for low magnetic fields
S. Salem-Sugui, A. D. Alvarenga, R. D. Noce +4
We report on the magnetic properties of a special configuration of a FeRh thin film. An anomalous behavior on the magnetisation vs. temperature was observed when low magnetic field…
Vortex dynamics as a function of field orientation in BaFe1.9Ni0.1As2
S. Salem-Sugui, L. Ghivelder, A. D. Alvarenga +3
Vortex dynamics in a multiband anisotropic superconducting such as the Fe based superconductors, is interesting and potentially important for applications. In this study we examine…
Flux-creep in the second magnetization peak of BaFe{1.9}Ni{0.1}As2 superconductor
S. Salem-Sugui, L. Ghivelder, A. D. Alvarenga +3
Flux-creep data was obtained for fields along the second magnetization peak observed in M(H) curves of BaFe{1.9}Ni{0.1}As2 for H||c-axis. H||ab-planes and H forming a 45 degrees an…
Magnetic phase diagram of the layered superconductor Bi{2+x}Sr{2-x}CuO{6+δ} (Bi2201) with Tc~7 K
S. Salem-Sugui, A. D. Alvarenga, J. Mosqueira +5
We report on magnetization measurements performed on a single crystal of Bi{2+x}Sr{2-x}CuO{6+δ} with Tc\sim7 K for H||c-axis. The isofield M(T) curves show a large reversible regio…
