متن کاملX-Ray Absorption Spectromicroscopy of Aqueous Samples
X-ray PhotoElectron Emission Microscopy (X-PEEM) has found numerous applications in the surface microchemical analysis of materials science and biological specimens. We have reconfigured the MEPHISTO X-PEEM instrument, installed at the UW-Synchrotron Radiation Center, to measure true x-ray transmission spectra by converting transmitted photons to photoelectrons via a thin photocathode layer of ...
متن کاملX-ray absorption and magnetic circular dichroism of graphene
We present systematic investigations of the electronic and magnetic properties of the graphenel Ni( Ill) system by means of x-ray absorption spectroscopy (XAS) and magnetic circular dichroi sm (XMCD) at the Ni L2,3 and C K absorption edges. The XAS CIs -> 1/'* , u* spectra show dramatic changes as the angle, il', between the electrical vector of light and normal of the sample is varied reflecti...
متن کاملX-Ray Magnetic Circular Dichroism Studies on CeNi4B
The CeNi4B compound is a mixed-valence system. It is a paramagnet with μeff = 0.52 μB/f.u. and the paramagnetic Curie temperature θ = −10.7 K. In the present research we complete our previous magnetic susceptibility and X-ray photoemission measurements with new studies by the X-ray magnetic circular dichroism method. The observation of the Ce M4,5 edges carried out with X-ray magnetic circular ...
متن کاملFemtosecond X-ray magnetic circular dichroism absorption spectroscopy at an X-ray free electron laser.
X-ray magnetic circular dichroism spectroscopy using an X-ray free electron laser is demonstrated with spectra over the Fe L(3,2)-edges. The high brightness of the X-ray free electron laser combined with high accuracy detection of incident and transmitted X-rays enables ultrafast X-ray magnetic circular dichroism studies of unprecedented sensitivity. This new capability is applied to a study of...
