Local magnetic properties and magnetostatic interactions of permalloy microstripes

Abstract

Local magnetic properties of permalloy microstripes with the different aspect ratio (varying from 2 to 15) were investigated by scanning Kerr microscopy. The local magnetic properties of the microstripes were discovered to depend on their sizes and a location of the test parts in the microstripe. It was found that the local magnetic properties and the distributions of the magnetization components of the examined microstripe arrays are mainly determined by the inhomogeneous dipolar fields.
