Spin-Polarised Current
Development of a nano-spin motor
Project details
In order to implement a highly efficient and miniaturised motor or actuator into recent nano-robotics and nano-electro-mechanical systems, a new nano-scale motor will be developed and demonstrated in this project. The proposed nano-spin motor will utilise the rotation of a magnetic moment in a nano-magnet associated with the orientation of spin-polarised electrons through spin torque. This motor enables us to control rotation of a magnetic moment in a nano-scale permanent magnet electrically and can be used as a fundamental block for future nano-system design.
This project will be carried out under the close collaboration with Profs. Yuzo Ohno and Hideo Ohno at the Laboratory for Electronic Intelligent Systems, Research Institute of Electrical Communications, Tohoku University.

Efficient spin voltage/current generation in a ferromagnet/semiconductor lateral spin-valve
Project details
The goal of this project is to fabricate
spintronic devices based on either a pure spin current or a pure spin voltage, which are expected to offer fundamental functions for next-generation nanoelectronic device applications.
This project will be carried out under the close collaboration with Profs. Yuzo Ohno and Hideo Ohno at the Laboratory for Electronic Intelligent Systems, Research Institute of Electrical Communications, Tohoku University. A successful PhD candidate will spend approximately 3 months in Tohoku University to fabricate spintronic nanodevices with using state-of-the-art nano-fabrication facilities.
The interfacial properties as well as transport properties will be characterised by ultra high resolution (1Å) Field Emission Transmission Electron Microscope and low-temperature measurement set-up in collaboration with Prof. Kevin O'Grady in Physics.
