RIM practicum (191228280)

Course code: 191228280

Bachelor Electrical Engineering

(3rd year, semester 1, quarter 1)

Contributing teachers for NE:

Dr. ir. Michel P. De Jong (M.P.deJong[at]utwente.nl)

Content

The group NanoElectronics contributes by offering a lab course on the fabrication and characterization of Giant MagnetoResistance (GMR) sensors.

Modern hard disks are equipped with read heads that detect magnetic bits using “giant magnetoresistance” (GMR) sensors. The GMR effect (Nobel Prize for Physics 2007) only occurs in ultrathin (several nm) multilayers of metals with different magnetic properties. As such, GMR sensors are among the first applications of nanotechnology. During the lab course, GMR sensors will be fabricated and tested. A large number of fabrication methods will be encountered, such as photolithography, sputter deposition of ultrathin films, ion beam etching, and lift-off techniques. In addition, the relation between electrical and magnetic properties of metal films at the nanoscale will be investigated.
