Ultimate Magnetic Recording “Challenge to super terabit recording” Various technology which aimed at the recording density of 1 terabit per square inch (1Tbit/in2) made a present target has been proposed to realize a hard disk drive (HDD) of large storage capacity. Last year, there were announcements the areal recording density of HDD achieved 612 Gbit/in2 and 803 Gbit/in2by present perpendicular recording system and by using a descrete track media. And it is expected that 1 Tbit/in2 will be realized within several years. To achieve an areal recording density of the super terabit, the ultimate technology which controls the nanometer and a nanosecond, in each technology like microfabrication, a smaller bit evaluation, and […]

Detection of Magnetic Nanoparticles and Its Biomedical Applications Research and development of biomedical applications of magnetic nanoparticles have been activated from fundamental subjects to clinical tests.

Recent Studies on Cooperative Phenomena between Magnetics and Optics Since Michael Faraday discovered the rotation of the plane of polarized light in a magnetic field, magneto-optical effects are used to realize Kerr effect microscopes, optical isolators and magneto-optical disks. Recently, interaction between magnetics and optics enables to control magnetization by photons as well as controlling optical properties by magnetization, and we are concerned with new cooperative phenomena and devices such as metamaterials, nanoparticles, spin injection and detection in spin-LED, and manipulation of magnetization by light. In this joint symposium, researchers actively working in this field will give talks on their latest results and discuss the new relationship between magnetics and […]

Recent Topics of Research in Magnetism and Industrial Applications using Neutron Scattering and Prospective View with the World Highest Neutron Source at J-PARC The neutron is an indispensable and nondestructive probe particularly for the investigation of magnetism. The Materials and Life science experimental Facility (MLF) with the world highest pulsed neutron source in Japan Proton Accelerator Research Complex (J-PARC) is now under construction. The first neutron beams are scheduled to deliver to the several neutron spectrometers installed at MLF in May, 2008. Much progress in research of magnetism is expected using intense pulsed neutrons at this facility in near future. This symposium provides an opportunity to introduce the performance of […]

Fundamental physics and device application of spin functions in semiconductor Recent intensive studies on “spintronics” grow the understanding about spin-function in semiconductors. The coverage of the research is expanding to include electronics, magnetics and optics. Additionally, the crossover between magnetic “metal” and “semiconductor” plays an important role to realize highly-functional spintronic devices. The spintronic devices made of semiconductor are also very compatible with the existing electronics technology. In this symposium, we will focus on the spin function of semiconductor from the viewpoint of the fundamental physics and application. We invite the lead scientists in this field and discuss the future devices. We very much look forward to your participation. Date: […]
