We had the pleasure to welcome Thierry Valet on February 11 and 12. If it was that he was not completely unaware of German Carnival traditions, we do not know. In any case, he was lucky not to wear a tie when he took off for a meeting with Jairo Sinova and Matthias Kläui. Mr Valet is known for the Valet-Fert Theory and Model on giant magnetoresistance in CPP geometry and the application of his research in spin engineering.
