Mesures de transport

L'origine d'un phénomène de transport est l'application d'une force dont l'origine peut être variée (champ électrique ou magnétique, gradient de concentration, de pression etc ...)
Sous la rubrique "mesures de transport" sont rassemblées différentes techniques de mesures associées qui peuvent être des mesures de flux (chaleur, particules, charges : courant électrique, etc ...), ou des méthodes statistiques.

Among the many types of liquid crystals (LCs), planar disk-like molecules such as triphenylenes are known to exhibit columnar mesophases. An example of such compounds are 2,3,6,7,10,11-hexakis-alkoxy-substituted triphenylenes, hereafter noted Tn where n indicates the number of carbon atoms in the alkyl chains. Tn molecules consist in flat polyaromatic cores symmetrically surrounded by flexible n-carbon side chains (Figure 1).
Fe3O4 is a very attractive material for applications involving spin-dependent transport at room temperature as this ferromagnetic oxide has a high Curie temperature (Tc= 858 K) and is predicted to be half-metallic. However, the potential applications of Fe3O4 layers in devices relies on the assumption that the magnetic and transport properties in the thin films are similar to those in the bulk material.

Spin electronics is a new field of research which associates two domains of physics: magnetism and electronics. In the last decade, effects related to spin dependent transport like giant magnetoresistance (GMR) and tunnelling magnetoresistance (TMR) in magnetic heterostructures have stimulated a considerable interest. These physical properties can be exploited in a variety of advanced devices such as highly sensitive magnetic sensors (e.g.
