Magnetic Materials (Permanent Magnets, High Frequency Materials, Microwave Absorbers)
update：2020-06-16
Features
The objectives of my researches are the development of high performance magnets and improvement of their magnetic properties. I have already developed following high performance magnets, such as Nd-Fe-B magnets using didymium, Sm-Fe-N high coercive powders prepared by HDDR and Fe-Cr-Co magnets. Recently, I have studied about the reduction of Dy content in Nd-Fe-B magnets for the use of HEV and have succeeded to develop high coercive Dy-free Nd-Fe-B sintered magnets by decreasing the grain size. I have also developed new kinds of microwave absorbers for the use in the frequencies of GHz range using permanent magnetic materials or nanoparticles.Targeted Application(s)/Industry
High performance magnetic materials can be used in many applications in automobile, home electronics, IT and medical industries. We hope to conduct collaborative researches with companies producing magnetic materials for the use in these applications, which aims to improve magnetic properties or to develop new magnetic materials.Researchers
