Abstract

We report on the dynamic properties of mesoscopic magnetic objects. Such objects have dimensions somewhat larger than the magnetic exchange length ξ. This leads to relatively simple and stable patterns of the magnetization, which can be excited using magnetic field pulses. The subsequent dynamics can be studied using X-ray-based magnetic microscopy. We show examples of high symmetry structures where the dynamics is relatively simple and can be analyzed quantitatively in terms of amplitude, frequency, damping, and symmetry.Intentional defects allow modifying specific modes. When using high amplitude excitations, the magnetization in such structures can be switched.
