Abstract
The dynamics of the micro magnetic switch driven by optical heating is simulated. By using Three Dimensional Finite Difference Time Domain (FDTD) program newly developed and FEM, a small armature composed by thermo-sensitive magnetic film can operate faster than 0.05ms by heating power of 7mW or less, Bi-stable operation is also confirmed.
