A new way of controlling local magnetic field in a nano junction


A new proposal is given to control local magnetic field in a nanojunction. In presence of finite bias a net circular current is established in the nano ring which induces a magnetic field at its center. Allowing a direct coupling between two electrodes, due to their close proximity, and changing its strength we can regulate circular current as well as magnetic field for a wide range, without disturbing any other physical parameters. We strongly believe that our proposal is quite robust compared to existing approaches of controlling local magnetic field and can be verified experimentally.


Santanu K. Maiti is an Assistant Professor of Physics at Indian Statistical Institute, Kolkata, India. He has received his Master's degree in Physics from the University of Calcutta, India, and then he joined to Saha Institute of Nuclear Physics (SINP), India, for his doctoral work. His research interests mainly focus on Quantum Transport in Meso-scale and Nano-scale Systems. He has published several papers in peer-reviewed International Journals, out of which more than sixty five papers he has published independently. He has also published many Reviews, co-edited a Book in Springer Series and contributed a chapter to a Book. He has also been working as Associate Editor, Section Editor as well as Editorial Board Member in several International Journals over the past many years.
