Magnetic fields and living body – interaction among them, medical applications – The magnetic fields are utilized in our daily life in various ways. Recently, high magnetic fields are applied not only for scientific use but also for common use such as MRI, therefore, the opportunity of exposure against high magnetic fields is increasing for people. Even though the effects of magnetic fields on human or living bodies have attracted much attention through the ages, the understandings about the interaction among them were deepened only recently. Owing to this improvement of understandings, the applications of magnetic fields are increasing such as a tool to investigate the brain function, or as […]

New Developments of High Performance Magnetic Sensor Applications The sensor, which can detect information or energy, is one of the key devices to support safe, secure and convenient life in highly information-oriented society. Magnetic sensors, which detect electromagnetic fields, have been used in many applications because of noncontact technology. For example, classifying the sensors in terms of sensing object, the sensors to detect magnetic field, are popular devices. Recently, achievements of high performance magnetic sensors lead to the new technology developments such as navigation technologies by electric compass, environment monitoring technologies, nondestructive detection technologies, and medical diagnosis technologies. The 167th Topical Symposium of the Magnetics Society of Japan aims providing […]

Magnetics for the environment and the energy conservation What can we do to solve the issues? The Fourth Assessment Report of the International Panel on Climate Change (IPCC) and the Working Group I Report “The Physical Science Basis” (2 February 2007 by the Ministry of Education, Culture, Sports, Science, and Technology; Ministry of Economy, Trade, and Industry; Japan Meteorological Agency; and Ministry of the Environment) concluded that global warming and climate change are progressing and that global warming is increased by human-induced greenhouse gas emission. Applying technology to prevent the disruptive effects of global warming has been seriously discussed, and many policies concerning science and technology have been established. Recycling […]

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 […]
