Nanomagnets are very promising structures for magnetic data storage. However, it is found that during exposure to ambient oxygen for processing, a nanomagnet develops a sidewall oxide layer that is detrimental for its magnetic properties. The problem can be solved by deposition of a metal layer (aluminium) that reduces and almost eliminates the problem.
