Magnetization process of zigzag shaped Co wires

We report on the magnetization process of submicron zigzag shaped Co wires fabricated by electron-beam lithography. The field dependent magnetizations and resistivities show intrinsically different types of magnetization swit ching by changing the orientation of the fields. The magnetization switchin g profiles are consistently interpreted based on the? magnetostatic energet ics involving domain wall energy created at the zigzag corners. The present results support our previous picture for the reduction of the resistivity due to domain walls.
