Bistability of (Ga,Mn)As Ferromagnetic Nanostructures Due to the Domain Walls Switching

Andrearczyk, T. ; Wosinski, T. ; Makosa, A. ; Figielski, T. ; Wrobel, J. and Sadowski, Janusz LU (2009) 4th Workshop on Quantum Chaos and Localisation Phenomena 116(5). p.901-903
Abstract
We designed and investigated four-arm nanostructures, composed of two perpendicularly crossed stripes, fabricated from ferromagnetic (Ga,Mn)As layer by means of electron-beam lithography patterning and chemical etching. The nanostructures exhibit a bistable resistance behavior resulting from two configurations of magnetic domain walls in the central part of the structures. We demonstrate a possibility of switching between two stable resistance states in zero magnetic field by applying a pulse of either weak magnetic field or electric current through the structure.
