Magnetic Domain Wall Networked Films – Configurational Switching for Tunable Magnetization Dynamics by Perforated Thin Films (Adv. Mater. Technol. 7/2024)

Tunable Magnetization Dynamics In article number 2301959 by Jeffrey McCord, Rasmus B. Holländer, and Cai Müller, bimodal dynamic permeability characteristics in punctured magnetic films are tuned by tunable networks of magnetic domain walls. In this way, magnetization dynamics can be altered with small interventions, enabling the design of energy-efficient configurational microwave devices. The configurational spatial magnetic resonances confined by the magnetic domain walls are verified by dynamic magneto-optical Kerr microscopy with picosecond time resolution.
