Abstract:

Magnetization reversal mechanisms and the impact of magnetization direction are studied in square arrays of interconnected circular permalloy nanorings using magnetooptical Kerr effect, local imaging, numerical simulations, and transport techniques.

Keywords: magnetic nano-structures; magnetization reversal; magnetoresistance; nano-rings
