Magnetic sensors and storage devices

In this talk, I will present research efforts recently initiated in my laboratory to develop novel magnetic devices. These include biosensors and solid state memory using magnetostrictive thin films. The sensors are based on magnetic bead labeling of target biological and chemical agents, and are envisioned for application in counterterrorism monitoring and bio-medical diagnostics. We are also working on a novel solid state magnetic memory in which the storage and retrieval of data is accomplished by surface acoustic waves (SAWs). SAWs are mechanical stress waves that travel along the surface of a medium. The principles of reading and writing data exploit the interaction between the SAW induced stress and the magnetization of a magnetostrictive storage medium.
