Output errors of power amplifiers, hysteresis and creep error of PZTs and coupling error among the actuators are the critical factors affecting the motion accuracy of micromanipulator.
The magnetization behavior and inter-grain exchange coupling of the ribbons were studied in terms of the initial magnetization curves, the minor hysteresis loops and the recoil loops.
