Magnetic susceptibility measurement and modelisation of a novel compound

Bastien Dalla Piazza

We study the magnetic susceptibility of the novel metal-organic framework [Cu3(mu3O)(mu3trz)3(OH)(H2O)6. The magnetic susceptibility is measured using a SQUID magnetometer. Exact diagonnalization and mean Field theory are then used in an attempt to Fit the ...

Thermoelectric power in Bi2Sr2Ca1-xPrxCu2O8+delta in a wide temperature range

László Forró, Neven Barisic

Scientific conference paper We report thermopower and electrical resistance measurements of the high-temperature superconductor Bi2Sr2Ca1-xPrxCu2O8+delta (0 < x < 1) in a wide temperature range from 600 K to superconducting transition temperature (critical ...

Spin dependent thermoelectric effects in magnetic nanostructures

Santiago Serrano Guisan

The aim of this thesis work was to obtain a deeper understanding of spin-dependent transport by the study of mixed effects of heat and charge currents in magnetic nanostructures. Indeed, even thermodynamics establish a relationship between both currents, n ...

Study of novel electronic conductors

Neven Barisic

This thesis presents the results of a concerted effort to understand the complex array of physical properties exhibited by the BaVS3 family of materials. As a 3d1 system, BaVS3 displays a unique collection of correlation-driven phenomena, including a metal ...

Spin-dependent thermopower in Co/Cu multilayer nanowires

Jean-Philippe Ansermet, Aurore Rudolf

The magnetic field dependence of the thermoelectrical power of a series of Co/Cu multilayered nanowires grown by electrodeposition in a polymer matrix is almost that predicted by the Mott formula in the temperature range of 15300 K. Application of the two- ...

Figure of merit of quasicrystals: the case of Al-Cu-Fe

Davor Pavuna

Quasicrystals exhibit low thermal and moderate electrical conductivity, accompanied by a relatively high absolute magnitude of thermopower, which makes them suitable candidates for use as thermoelectric devices. Theoretical explanations of electrical and t ...

Thermoelectric power in undoped hydrogenated polymorphous silicon

Raphaël Butté

Thermoelectric power and conductivity measurements have been made as a function of temperature on a new nanostructured material, hydrogenated polymorphous silicon (pm-Si:H). The thermoelectric power is negative, so electrons are the dominant carriers. The ...

Reversible Gelation of Poly(dimethylsiloxane) with Ionic and Hydrogen-Bonding Substituents

Harm-Anton Klok

Poly(dimethylsiloxane) copolymers containing a small fraction of carboxylic acid or Zn-carboxylate groups were prepared and compared regarding reversible gelation by hydrogen-bonding and ion-pair interaction. The polymers were synthesized by condensation o ...

Evidence for improvement of critical current by Ag in YBaCuO-Ag thick films

Davor Pavuna

The evidence is reported for enhancement of critical current density Jc in YBa2Cu3O7-δ thick films with the addition of Ag, which is correlated with improvements in structural properties. An improvement of 50% in Jc (up to ~500 A/cm2 at T=4.2 K) was obtain ...
