Magneto-elasticity and magneto-acoustics in the ferromagnetic semiconductor (Ga, Mn) As

, 2020
Ce travail de thèse est consacré à l'étude de la dynamique d'aimantation excitée par des ondes acoustiques dans des couches de (Ga,Mn)As. Dans la première partie, nous présentons une étude à la fois expérimentale et théorique sur l'origine de la forte ...

Magneto-acoustic coupling: Physics, materials, and devices

Acta Physica Sinica
Acoustic wave in solid has two modes of propagation: the bulk acoustic wave (BAW), which propagates inside solid in the form of longitudinal or transverse wave, and the surface acoustic wave (SAW), which is generated on the surface of solid and propagates along the surface.

Localised excitations in long Josephson junctions with phase-shifts with time-varying drive [PDF]

In this project, we consider a variety of ac-driven, inhomogeneous sine-Gordon equations describing an infinitely long Josephson junctions with phase shifts, driven by a microwave field.

Optical detection of magneto-acoustic dynamics

, 2018
Ce travail se situe dans le contexte de l’utilisation des ondes de spin comme vecteur d’information. Il explore la possibilité d’exciter l’aimantation dans de fines couches ferromagnétiques grâce au couplage magnéto-élastique. Cela permettrait un adressage non-inductif, efficace, et distant des ondes de spin. Dans un premier volet, nous avons développé

Magneto-Acoustic Resonances in Antimony

Magneto-Acoustic Resonances in Antimony
application/pdf Spike-like sharp absorption peaks have been observed in an ultrasonic attenuation coefficient of antimony in a weak magnetic field range. This type of resonance is not caused by the electron in an extremal orbit as has been observed in many cases of geometric resonance, but it is probably due to the particular kind of selective coupling
