Studies of Nanoconstrictions, Nanowires and Fe3O4 Thin Films

This work examines electrical and magnetic properties in nanometric materials with a range of scales: atomic-sized nanoconstrictions, micro- and nanowires and thin films. It describes an approach to tailoring magnetic and other properties of nanostructures.

This work constitutes a detailed study of electrical and magnetic properties in nanometric materials with a range of scales: atomic-sized nanoconstrictions, micro- and nanowires and thin films. Firstly, a novel method of fabricating atomic-sized constrictions in metals is presented; it relies on measuring the conduction of the device while a focused-ion-beam etching process is in progress.

Describes promising new approach to tailoring magnetic and other properties of nanostructures Potentially useful in diverse applications of nanotechnology Nominated as an outstanding contribution by the University of Zaragoza Includes supplementary material: sn.pub/extras
