Ono Teruo

In the late 1990s, Teruo Ono was one of the first researchers to develop nanotechnology processes for the formation of magnetic nanostructures from common magnetic materials and launch them into practice. As a result, this has lead to an understanding of the way magnetic and transport properties of such nanostructures manifest completely different characteristics compared to their 3D counterparts. Over the last ten years, the researcher has managed to measure the velocity of the domain wall in submicron-wide magnetic wires and observe magnetic vortex cores in magnetic nanodiscs. After these landmark discoveries, Professor Ono continued to retain academic leadership in the domain of magnetic nanostructures, and in the mid-2000s he initiated the research of the interaction between electric current and magnetisation intensity in magnetic nanostructures, thus laying the groundwork for the creation and development of spin-based nanodevices. In particular, he has demonstrated that magnetic domain walls in magnetic nanowires can be set in motion without the need to use an external magnetic field, while the direction of vortex core polarisation in magnetic nanodiscs can be changed by applying current pulses. These key discoveries have lead to the development of multidigit memory based on magnetic domain walls and vortex-based memory: the researcher's team has demonstrated prototypes of devices.

In more recent times, Professor Ono has been developing a research direction within which an enhancement of the spintronics phenomena is achieved by the supplementation of electrons with an additional orbital degree of freedom, hence forming a new field called spin-orbitronics. It is expected that the research of spin-orbitronic systems will allow to develop high-speed and energy-efficient spin-electronic devices in the near future. In particular, the researcher has studied the possibility of the extension of the range of materials for spintronics from common ferromagnetics to antiferromagnetics and ferrimagnetics. He has demonstrated that the magnetisation intensity of an antiferromagnetic or a ferrimagnetic can be efficiently controlled using spin-orbital interactions induced by a layer of a heavy metal that is in contact with the magnetic layer.
