Dynamics and Relaxation of Magnetization The magnetization reversal is the most important technology for the developments of the spintronics technology. In order to control the reversal, it is indispensable to understand the dynamics and relaxation of the magnetization. Such researches have overlap with the leading-edge spin-current phenomena, such as spin-torque magnetization reversal, spin-Hall effect, Hanle effect and so on. The dynamics and relaxation are the common issue in the spintronics studies. In this symposium, we are inviting speakers studying on the frontline of research on spin dynamics and relaxation. We hope to generate exciting and stimulating discussion among those interested in this field. Date: March 22, 2012 (Thu) 13:00-17:15 Venue: […]

Light and Magnetism in Meta-materials Macroscopic materials consisting of artificial components much smaller than the wavelength are called meta-materials. Meta-materials enable us to realize the intriguing wave behaviors, which we have never observed in nature; for example, a negative refractive index or an invisible cloak using electromagnetic meta-materials in the microwave region. In this symposium, we are inviting speakers studying on the frontline of research into optical and magnetic properties of meta-materials. We hope to generate exciting and stimulating discussion among those interested in this field, relating to the possibilities of meta-materials.

Advanced Technology for Future Information Storage The magnetic recording system such as HDD comes to do the kernel of the information storage technology, and is progressing to the field where the application is quite new on a digital information age. Moreover, the information storage is requested to take not only the magnetic recording technology but also other storage technologies, and to be discussed widely. In this symposium, we will focus on the advanced technology for future information storage. Though magnetic recording technologies are placed as a main stream, the symposium where new information storage technologies are able to be discussed actively is planned. It was postponed due to the earthquake […]

The present status and future prospects of biomedical applications of magnetic nanoparticles […]

Electromagnetism of nano-structured materials Recent progress in the fields of meta-materials and spin-current using nano-structured materials has led a movement towards the re-consideration of magnetic permeability and electromagnetism of matter. Much attention has been paid to this movement also from the view point of near-field-assisted magnetic recording technologies. On the other hand, magnetic materials with large permeability have been intensively studied so far by members of the MSJ. This symposium is open for the discussion of “classical permeability” and “a new aspect of permeability” and to promote the novel research field of electromagnetism in nano-structured materials. In this symposium, we hope to generate exciting and stimulating discussion among those interested […]

The Physics of the “Spin-Crossover” The oxides and the complex including the transition metal have the crucial role as ceramics, functional polymers and a biological material such as the haem-protein. The d-electrons of the transition metals enclosed by the ligand dominants the characteristic of these materials and d-electrons will take a variety of spin arrangement, which is correlated with the difference of the electronic state. That is, the spin state is united strongly with the electronic state. Moreover, if the spin arrangement can be changed by external stimulation, the change in variegated physical properties accompanied with the change of magnetism can be realized through the change of the electronic state.
