Research on Novel Superconducting Oxides


Our group has focused efforts on the understanding of both the intergranular and intragranular components of High-TC oxides. This can be achieved by a systematic study of transport properties of these materials in both low and high applied magnetic fields. Thus, we have performed magnetic field and temperature dependency of electrical resistivity in High-TC cuprates.  In addition to these characterizations, we have also extracted interesting information regarding boundaries lines in the the H x T phase by performing a kind of Barkhausen transport-noise measurements in polycrystalline samples with grains aligned along the c-axis.

The current research projects also include a systematic study of the coexistence between magnetic ordering and superconductivity in Ru-based cuprates.
