Evidence for a Magnetic Seebeck Effect

Jean-Philippe Ansermet, Sylvain Bréchet, Francesco Antonio Vetrò, Elisa Papa

The irreversible thermodynamics of a continuous medium with magnetic dipoles predicts that a temperature gradient in the presence of magnetization waves induces a magnetic induction field, which is the magnetic analog of the Seebeck effect. This thermal gr ...

Local Excitation of Magnetostatic Modes in YIG

Jean-Philippe Ansermet, Elisa Papa

Described are ferromagnetic resonance (FMR) studies of the long wavelength magnetostatic wave modes of a single crystal yttrium iron garnet (YIG) slab magnetized by an in-plane field. A resonant circuit comprising a coil, 50 m in diameter, is used to excit ...

Biexciton emission and crystalline quality of ZnO nano-objects

Jean-Philippe Ansermet, Benoît Marie Joseph Deveaud, Jean-Daniel Ganière, Pierre Stadelmann, Pierre Michel Corfdir, Anas Mouti, Elisa Papa

The design of cost-effective standards for the quality of nano-objects is currently a key issue toward their massive use for optoelectronic applications. The observation by photoluminescence of narrow excitonic and biexcitonic emission lines in semiconduct ...
