Abstract

The micromagnetics and galvanomagnetic effects in Permalloy honeycomb nano-network were investigated using magnetic force microscopy (MFM) and magnetoresistance measurements. MFM showed that the magnetic properties of the system can be analyzed as a frustrated system constructed by magnetic moments in the wires. It was also observed that the magnetic properties of the system corresponds to the Ising spin model with a kagome lattice. Also from magnetoresistance measurements, it was clarified that the system behaves as a nanoscale ice-rule system which governs the magnetization switching process. But the ice rule type interaction disappeared with reducing magnetic energy at the vertices.
