Abstract
This study reports reproducible, ten thousand to hundred thousand percent ballistic magnetoresistance (BMR) effect in stable electrodeposited Ni nanocontacts at room temperature and in fields of only a few hundred oersteds. Experimental observation of Ni whiskers and nanoconstrictions within these whiskers formed during electrodeposition points towards a picture of multiple ballistic, quasi-ballistic, and diffusive conductors acting in series and parallel to give rise to the observed large BMR effect, instead of a single, monolithic nanocontact.
