Enhanced superconductivity, Kondo behavior and negative-curvature resistivity of oxygen-irradiated thin films of aluminium
E. H. C. P. Sinnecker, M. M. Sant'Anna, M. ElMassalami
We followed the evolution of the normal and superconducting properties of Al thin films after each session of various successive oxygen irradiations at ambient temperature. Such ir…
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…
Ion-beam modification of the magnetic properties of GaMnAs epilayers
E. H. C. P. Sinnecker, G. M. Penello, T. G. Rappoport +5
We study the controlled introduction of defects in GaMnAs by irradiating the samples with energetic ion beams, which modify the magnetic properties of the DMS. Our study focuses on…
