Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
A technology for the fabrication of bismuth Hall sensors integrated on SU-8 cantilevers has been developed in this project. Hall sensors with active area of 2 x 2 μm2 (Fig.2) are produced with lift-off and resized to 200 x 200 nm2 (Fig.3) with the FIB. SU- ...
Using a density functional approach, we study structural and magnetic properties of small Fe-n clusters (nless than or equal to8) deposited on a MgO(100) substrate. Upon deposition, the clusters closely preserve their gas-phase structure. The magnetic mome ...
At room temp. (1) is a green paramagnetic liq. under a blue gas, that freezes to a black diamagnetic solid, which consists of tetramers of (1). The enthalpy of fusion, vaporization and sublimation are similar to those expected for a diamagnetic material, i ...
Abstract We study the diamagnetic surface currents of particles in thermal equilibrium submitted to a constant magnetic field. The current density of independent electrons with Boltzmann (respectively Fermi) statistics has a gaussian (respectively exponent ...
This thesis is dedicated to the memory of my late professor A.R. Mackintosh — meant as a student’s tribute to his work of great insight. Through our unfortunately short acquaintance I owe Allan my interest in the field of solid state physics in general and ...
We report on X-ray photoemission of core levels, valence band studies using angle-integrated photoemission, and magnetization measurements of ruthenocuprate and SrRuO3 polycrystalline samples. The data indicate that the RuO2 planes are the source of the en ...
