Research

You may have used to play with magnets in your childhood and still have some magnets attached to your fridge. The object of our research is also magnets. Does it sound boring? In fact, our magnets are very interesting and very different from your daily magnets because our magnets are ultra-thin at a nano-scale in which intriguing phenomena, such as interface effects and the spin-orbit coupling, start to clearly come out.

Also, another import object is spin. Spin is an intrinsic property of electrons and responsible for the magnetism of magnets. Because you may have met the term "spin" in your quantum mechanics class for the first time, you may feel that spin is something very difficult and vague. However, the fact that every electron has spin means you can get spins whenever you have electric currents. How? Just apply voltage with a battery! Then, you will find spins in your laboratory.

To sum up, we explore the physics of the ultra-thin magnetic materials and spins, particularly, when the magnets meet spins of electric currents.
