Circular dichroism

First page of the paper published in "nature" dealing with EMCD (Nature 441 (May 2006), pp. 486-488).

Magnetic circular dichroism (MCD) was first proven for electrons in 2003 theoretically (C. Hebert und P. Schattschneider, Ultramicroscopy 96 (2003), pp. 463-468). Prior it was accesible only for X-ray spectroscopy. The experimental proof succedded 3 years later and found a big echo within the EELS-community. Since then the spatial resolution of EMCD was improved by the team of USTEM from more than 200 nm to less than 2 nm. It is now possible to study the magnetic behaviour of interfacial atoms in magnetic multilayers.

One important research topic of USTEM is therefore - beside valence EELS and low voltage EELS - the theoretical and experimental description of EMCD in order to keep on top on this topic.

Ein Forschungsschwerpunkt von USTEM liegt daher - neben der  - in der experimentellen und mathematischen Beschreibung des Zirkulardichroismus, um auch hier weiter federführend zu bleiben.

On behalf of completeness a list of foreign literature can be found at the end of this page.

Literature

Recent literature from other research groups:

As can be seen, other EELS-research groups started working on this topic later than USTEM.  This demonstrates once the actuality of this topic and second it shows that USTEM has a lead over other groups in the determination of EMCD.
