Influence de la densité de trous sur la dynamique des charges et de l'aimantation du (Ga, Mn)As en couche

Show other versions (1)

Ce travail étudie le rôle de la densité de trous à l’équilibre sur la dynamique des charges et de la norme de l’aimantation de (Ga,Mn)As pour des densités de manganèse et d’impuretés fixées indépendamment. Des expériences « pompe-sonde » mettent en relation les dynamiques de réflectivité et d’angle...
