Professor / ISHIBASHI Takayuki
Prof. Ishibashi is a very friendly teacher who can easily consult with you. He offers a variety of advice on research and takes his student issues seriously despite being very busy. Especially when proceeding with research activities, he provides many opportunities for consultation. Therefore, We can be convinced and work hard on their research.

Research Content

Our laboratory conducts some research about magnetic materials
1. Preparation of magnetic garnet thin films by the metal-organic decomposition (MOD) method and evaluating its magnetic properties. we can make a high quality garnet thin film. In addition, we develop new thin film fabrication technology. Laser crystallization method (optical MOD) can reduce the heating on the substrate. The ultrasonic atomization method can apply to arbitrary shapes
2. Development of evaluation technology using the garnet thin film by magneto-optical measurement
3. Development of magneto-optical imaging technology. It is possible to visualize the magnetic field by the garnet thin films.

Development of evaluation technology using the garnet thin film by magneto-optical measurement.

A Day in the Lab

In Ishibashi Laboratory, his students will divide into groups according to major research themes and proceed with experiments. Seminars are held every Thursday. We will be presented with a weekly report on their research that a week and an English dissertation on their research. Ishibashi Lab. have cooperative relationships with domestic research institutes and overseas universities. We can actively interact with overseas researchers and learn about cutting-edge research. You are able to feel free to consult with the teacher or seniors. Therefore you can proceed with your research efficiently.
