The features of Barkhausen jumps in multilayer ferromagnetic films with crossed easy axes of magnetization

The Barkhausen jumps (BJs) of multilayer magnetoresistive stripes with crossed easy axes of magnetization (EAs) in ferromagnetic layers have been studies.

Description
Summary:	The Barkhausen jumps (BJs) of multilayer magnetoresistive stripes with crossed easy axes of magnetization (EAs) in ferromagnetic layers have been studies. Switching a strip in the threshold field H, is shown to be made by one or two BJs. A change in magnetoresistance Δ ρ/ρ corresponding to a big BJ is as great as ∼ 1.5%. The results of defining BJ parameters are: forms of individuals BJs, duration and probability of BJ appearance in the present field range are presented. The displacement speed of the domain boundary of reverse magnetization in the process of BJs reaching 300 m/s was evaluated.
