[PDF][PDF] Experiments on femtomagnetism

G Salvatella Orgillés - 2016 - research-collection.ethz.ch
When a ferromagnet is exposed to a femtosecond laser pulse, its magnetization is reduced
within less than a picosecond. This surprising effect has challenged the established theory …

Dynamique ultrarapide de l'aimantation dans les alliages de métaux de transitions et de terres rares

T Ferté - 2017 - theses.hal.science
Mon travail décrit la dynamique de l'aimantation pico et femtoseconde mesurée grâce à la
structure temporelle des rayons X. J'ai étudié la désaimantation ultrarapide des métaux de …
