Tunable magnonic frequency and damping in [Co/Pd]8 multilayers with variable Co layer thickness
TL;DR: In this article, the collective picosecond magnetization dynamics in [Co/Pd]8 multilayers with perpendicular magnetic anisotropy was observed and the damping coefficient α was found to be inversely proportional to the Co layer thickness.

TL;DR: All-optical time-domain detection of picosecond magnetization dynamics of arrays of 50 nm Ni(80)Fe(20) (permalloy) dots down to the single nanodot regime and one dominant resonant mode corresponding to the edge mode of the 50 nm dot with slightly higher damping is reported.

All-Optical Excitation and Detection of Picosecond Dynamics of Ordered Arrays of Nanomagnets with Varying Areal Density
TL;DR: In this article, optical excitation and detection of collective precessional dynamics in arrays of coupled Ni80Fe20 (permalloy) nanoelements with systematically varying areal density by an all-optical time-resolved Kerr microscope were demonstrated.

Magnetization reversal dynamics in clusters of single domain Ni nanoparticles
TL;DR: In this article, the magnetization reversal dynamics of clusters of single domain nickel nanoparticles are studied. But the results of magnetization reversals are completely different from those of the bulk nickel and single nickel particles in terms of the overall shape, coercive field, and saturation magnetization.
