Part of the Springer Proceedings in Physics book series (SPPHY,volume 169)

Abstract

We demonstrate the first generation of circularly-polarized high harmonics, which are bright enough for measurements of the x-ray magnetic circular dichroism (XMCD) at the M absorption edges of Fe, Co and Ni in the extreme ultraviolet range.
