Workshop Micromagnetic Theory & SANS

The workshop will be held at Forschungs-Neutronenquelle Heinz Maier-Leibnitz (FRM II) in Garching where experts in SANS and/or micromagnetics will meet and discuss the state-of-the-art in the field.

For interested participants we will organise a visit of the neutron guide hall with special focus on the SANS instruments. A full scale FRM II tour (including the experimental hall) is possible if requested. Please note that a valid passport is therefore inevitable.

Organising Committee:

Andreas Michels (University of Luxembourg)

Dmitri Berkov and Sergey Erokhin (INNOVENT Technologies)

Andre Heinemann (HZG)

Registration is necessary but there are no fees.
