Combination of electric fields and Joule self-heating is used to change the oxygen stoichiometry and promote oxygen vacancy drift in a freestanding (La,Sr)MnO 3 thin film microbridge placed in controlled atmosphere. By controlling the local oxygen vacancies concentration, we can reversibly switch our (La,Sr)MnO 3 -based microbridges from...

The development of thin film deposition techniques allowed the growth of new artificial materials leading to the discovery of new high Te superconducting compounds as infinite layer based superlattices [(BaCuO2)(m)/(CaCuo(2))(n)]). The order of the superlattice structure seems to be one of the crucial parameters to be improved so as to induce a...

The use of cryogenics micro calorimeters with Transition Edge Sensors for high-resolution spectroscopy for space applications puts several constraints on the detector's performances. Among several requirements, the long term stability of TES from a chemical and physical point of view is one of the most important. Iridium is a very interesting...

The beta-phase Zn4Sb3 has attracted much attention because of its high thermoelectric performance in the intermediate temperature range thanks to disorder in the Zn lattice site. In this work are presented structural, thermal, electric and thermoelectric characterization of Zn4Sb3 pure and Ag, Al doped, prepared by a simple synthesis....

The employment of superconducting thin films as electronic devices seems to be the most probable future application of these materials. For this application, thin films with extremely smooth surface and very good superconducting as well as structural properties are required. We deposited YBCO epitaxial thin films by pulsed laser ablation using...

We investigate the resistive switching behaviour of VO2 microbridges under current bias as a function of temperature and thermal coupling with the heat bath. Upon increasing the electrical current bias, the formation of the metallic phase can progress smoothly or through sharp jumps. The magnitude and threshold current values of these sharp...

We report the synthesis procedure and the chemical-physical characterization for the YNi2B2C superconductor. From magnetic measurements we show that this material is a type II superconductor. We value the penetration depth, the coherence length and so the Ginzburg -Landau parameter. Despite the low value of kappa (12), a very large region of...

Magnetic and electrical transport properties of artificially layered [(BaCuO2)(2)/(CaCuO2)(2)](N) superlattices grown by pulsed laser deposition have been investigated. It has been found that these superlattices have a metallic normal state resistivity with a transition temperature of about 74 K. The holes concentration, from Hall measurements,...
