Magnetic states and ferromagnetic resonance in geometrically frustrated arrays of multilayer ferromagnetic nanoparticles ordered on triangular lattices

摘要

We present a theoretical investigation of magnetostatic interaction effectsin geometrically frustrated arrays of anisotropic multilayer ferromagneticnanoparticles arranged in different spatially configured systems withtriangular symmetry. We show that the interlayer magnetostatic interactionsignificantly expands the opportunities to create magnetically frustratedsystems. The effects of the magnetostatic interaction in magnetization reversalprocesses and the possibility to control the ferromagnetic resonance spectrumin such systems are discussed.
