Publikováno v: Materials Science-Poland, Vol 33, Iss 3, Pp 639-643 (2015)
AlN films on a Si substrate were synthesized by magnetron sputtering method. A dual magnetron system operating in AC mode was used in the experiment. Processes of synthesis were carried out in the atmosphere of a mixture of Ar/N2. Morphology and phas

Publikováno v: SPIE Proceedings.
The multi-mJ, 21-nm soft-x-ray laser at the PALS facility was focused onto the surfaces of amorphous carbon (a-C) coatings, developed for heavily loaded XUV/x-ray optical elements. AFM (Atomic Force Microscopy) images show a 3-micrometer expansion of

Size-dependent magnetism of deposited small iron clusters studied by x-ray magnetic circular dichroism
Autor: Alexander Föhlisch, J. T. Lau, W. Wurth, M. Reif, R. Nietubyc̀
Publikováno v: Physical review letters. 89(5)
The size-dependent magnetic properties of small iron clusters deposited on ultrathin nickel films have been studied with circularly polarized synchrotron radiation. With the use of sum rules, orbital and spin magnetic moments have been extracted from
