Magnetization dynamics of nanostructures in strongly out-of-equilibrium regimes

ABSTRACT

This thesis aims at investigating, understanding and controlling the linear and nonlinear regimes of magnetization dynamics in individual nanostructures made of magnetic materials with very weak damping. An original near field microscopy technique developed in the host laboratory to detect the spin dynamics at the nanoscale will be employed to perform experiments, and analytical tools as well as micromagnetic simulations will be used for their interpretation. This work will take place in the framework of an ANR project whose goal is to demonstrate the manipulation of high amplitude coherent spin waves in devices combining concepts of magnonics and spintronics.

Keywords: magnetization dynamics; nanomagnetism; spintronics; magnonics; nonlinear dynamical systems

Methods: magnetic force microscopy; high frequency techniques; micromagnetic simulations
