    [Research Activities]
    1.Quantum Tunneling of Macroscopic Magnetization: A nonequilibrium double-well system may relax to the equilibrium state, either overbarrier or underbarrier. Our studies are concentrated on the tunneling processes and their time-dependent effect. Contributions of the mutual interactions and the intermediate states are also interested.
    2.Dynamic Reversal of Mesoscopic Magnets: To understand the inconsistent between the experimental data and reversal theory, we extend the linear theory to the nonlinear and chaotic regions. High frequency response shows that the magnetization reverses oscillatory and detailed analyses are still in progress.
    3.Mechanism of Tunneling Magnetoresistance: Spin-dependent tunneling of electrons gives a very large magnetoresistance, we are now studying the possibility of spin-filter to enhance the magnetoresistance.
    4.Mechanism of Exchange Bias in Spin-valve: The origins of spin valve type multilayers are studied, especially, the topological effects on the magnetic surface anisotropy and antiferromagnetic states are emphasized. Now we are concentrated on the mechanism of exchange bias. Ultimate goal is to find the easy way to build a giant magnetoresistance, low coercivity spin valve.
    5.Magnetic Recording Theory: Physical processes of the magnetic recording and their associated noises are interested. We currently are concentrated on the thermal noise of bycrystal media.

    I am currently involved in a highly successful research group carrying out computational and theoretical studies of magnetic materials within the Department of Physics, National Taiwan University. We have collaborated with a lot of experimental groups around the world in addition to our own departmental experimentalists. A very important and productive collaboration is with the experimental group in Institute of Physics, Academia Sinica. The interaction between theory and experiment generated by this collaboration makes a vital contribution to the development of both models and experimental techniques.

    My current research activities are focused on the following topics:

    I.Spin-dependent related problems: Spin transport from metallic system, insulating system, and final merges with semiconductor. All kind of exotic and interesting phenomenon from manipulating spin in media had been identified. We are concentrating on the 2DEG and spin pumping problems, we also interested in spin torque transfer and synchronization of the STOs.

    II. Dynamic Reversal of Mesoscopic Magnets: To understand the inconsistent between the experimental data and reversal theory, we extend the linear theory to the nonlinear and chaotic regions. High frequency response shows that the magnetization reverses oscillatory and detailed analyses are still in progress.

    III. Mechanism of Exchange Bias in Spin-valve: The origins of spin valve type multilayers are studied, especially, the topological effects on the magnetic surface anisotropy and antiferromagnetic states are emphasized. Now we are concentrated on the mechanism of exchange bias. Ultimate goal is to find the easy way to build a giant magnetoresistance, low coercivity spin valve.

    IV. Magnetic Recording Theory: Physical processes of the magnetic recording and their associated noises are interested. We currently are concentrated on the thermal noise of bycrystal media.
