Welcom to Yuasa laboratory !

Our purpose is to create new devices by utilizing Spintornics of the magnetic materials.
　The Internet of things (IoT) society is ready to spread in the world, which connects not only electric information but also the things and people. Because the both quality and quantity for IoT electronic devices become required higher than ever before, the more innovative technologies are needed and studied in various science fields.
　Spintronics of magnetic materials is one of candidates. In spintronics the spin plays an important role as well as electron. This is why Spintronics has the potential realizing the green devices without Joule energy loss.
　Now is the favorite time to study Spintronics toward the future electronic devices in order to contribute the future society.
