Resources

Lecture materials will be availble through the moodle system for registered participants.

Exercises /Lab

There will be both problem solving exercises and practical labs offered.

The labs will focus on thin film preparation, analysis and property measurements (thin film sputtering, XPS and XRR analysis, MOKE, GMR sensor lab). Lab groups/dates of experiment will be organized via moodle.
