How to easily write patterns in oxide thin films
What is it about?
A thin film of spinel ferrite is irradiated by the laser beam of a photolitographic machine. The laser spot modifies the irradiated regions in such a manner that bumps or holes appears. The crystallisation and the oxidation states are also modified in the irradiated regions.
Why is it important?
A way to prepare magnonic or magneto-photonic crystals.
