Abstract
Abstract- We have developed a magnetostrictive Fe6sC03s thin-film based micro-cantilevers using the micro-fabrication process. The cantilever stack consists of Si/SiO2/Fe6sC03s layers for actuation and thickness was controlled by silicon bulk micromachining process. High magnetostrictive and low-stress Fe/Co 65/35 composition was utilized in cantilevers. Magnetic properties of Fe6sCOJs films were investigated using a vibrating sample magnetometer and laser Doppler vibrometer. Micro cantilever dimensions were confirmed using scanning electron microscope. Magnetic actuation was performed by the applied magnetic field of 2000 Oe and tip deflection was monitored using the laser interferometry method. In-house de magnetic field set-up was developed which is compatible to laser Doppler vibrometer. Using a cantilever deflection method magnetostriction coefficient (1.) was found to be 135 ppm. The developed magnetostrictive cantilever is a very useful MagM EMS and low field sensing and actuation applications.
