Abstract

In this work, Laser-induced magnetization dynamics of nanostructured nickel films is investigated. The influence of the nanosize is discussed considering the time-scale of hundreds of femtoseconds as well as the GHz regime. While no nanosize effect is observed on the short time-scale, the excited magnetic mode in the GHz regime can be identified by comparison with micromagnetic simulations. The thickness dependence reveals insight on the dipole interaction between single nickel structures. Also, transient reflectivity changes are discussed.
