Antiferromagnetic coupling of TbPc2 molecules to ultrathin Ni and Co films

Beilstein Journal of Nanotechnology, 2013
The magnetic and electronic properties of single-molecule magnets are studied by X-ray absorption spectroscopy and X-ray magnetic circular dichroism. We study the magnetic coupling of ultrathin Co and Ni films that are epitaxially grown onto a Cu(100 ...

Observing heme doming in myoglobin with femtosecond X-ray absorption spectroscopy

Structural Dynamics, 2015
We report time-resolved X-ray absorption measurements after photolysis of carbonmonoxy myoglobin performed at the LCLS X-ray free electron laser with nearly 100 fs (FWHM) time resolution.

Characterization of Cobalt Co-Substituted M-Type Hexaferrites BaFe_12−x−yCo_xM_yO₁₉ with M = Sn, Zr, Hf

Inorganics
The study investigates Co2+/M4+ (Sn, Zr, Hf)-substituted M-type barium ferrites to understand phase formation, structural evolution and magnetic behavior. Ferrites with the general composition BaFe12−x−yCoxMyO19 were synthesized via sodium carbonate flux

Development of a flat jet delivery system for soft X-ray spectroscopy at MAX IV

Journal of Synchrotron Radiation
One of the most challenging aspects of X-ray research is the delivery of liquid sample flows into the soft X-ray beam. Currently, cylindrical microjets are the most commonly used sample injection systems for soft X-ray liquid spectroscopy.
