Quantum Nano-Scale Magnetics Laboratory, RIKEN, Otani Laboratory, ISSP, University of Tokyo

The Quantum Nano-Scale Magnetics Laboratory headed by Prof. Yoshichika Otani was launched in October 2001 as one of four laboratories in Single Quantum Dynamics Research Group at Frontier Research System in The Institute of Physical and Chemical Research (RIKEN).

Nano-scale magnets can have, according to their shape and size, ordered domain structures such as magnetic vortices and single-domains. Using experimental and theoretical approaches, we study static and dynamical magnetic properties of nano-scale magnets, to obtain a better understanding of the quantum behavior associated with domain wall displacement and magnetization reversal. Moreover, we employ spin injection techniques using nano-scale magnets as electrodes which provide spin-polarized current. This spin-injection induced magnetism will be applied to the development of spintronic devices.
