Femtosecond X-ray magnetic circular dichroism absorption spectroscopy at an X-ray free electron laser.

چکیده
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 all-optical magnetic switching dynamics of Fe and Gd magnetic sublattices in a GdFeCo thin film above its magnetization compensation temperature.

Magnetic dichroisms in absorption and photoemission for magnetic characterization in x-ray photoelectron emission microscopy
Magnetic contrast for the operation of a photoelectron emission microscope ~PEEM! with synchrotron radiation is provided by magnetic dichroisms. Besides the most frequently employed magnetic dichroism, magnetic circular dichroism in x-ray absorption spectroscopy, energy filtering of photoemitted electrons allows one to also use magnetic dichroisms in photoelectron emission as complementary cont...
متن کاملElectron correlation and charge transfer at the NiÕCo interface
The evolving magnetism and electronic structure at the Ni/Co interface have been studied using x-ray absorption spectroscopy ~XAS! and x-ray photoemission spectroscopy ~XPS! with circularly polarized x rays. Deposition of ultrathin Ni films on thin films of Co grown on Cu~001! results in an intensity enhancement across the Co L2.3 absorption edge. By comparison, the intensity of the Ni L2.3 edg...

A femtosecond pulsed laser system has been installed at the BL25SU soft x-ray beamline at SPring-8 for time-resolved pump-probe experiments with synchronization of the laser pulses to the circularly polarized x-ray pulses. There are four different apparatuses situated at the beamline; for photoemission spectroscopy, two-dimensional display photoelectron diffraction, x-ray magnetic circular dich...
متن کاملSpin state transition in LaCoO3 studied using soft x-ray absorption spectroscopy and magnetic circular dichroism.
Using soft x-ray absorption spectroscopy and magnetic circular dichroism at the Co-L(2,3) edge, we reveal that the spin state transition in LaCoO3 can be well described by a low-spin ground state and a triply degenerate high-spin first excited state. From the temperature dependence of the spectral line shapes, we find that LaCoO3 at finite temperatures is an inhomogeneous mixed-spin state syste...
متن کاملSimulation of magnetic circular dichroism in the electron microscope
As Electron Energy-Loss Spectroscopy (EELS) and X-ray Absorption Spectroscopy (XAS) probe the same transitions from core-shell states to unoccupied states above the Fermi energy, it should be always possible to apply the two techniques to the same physical phenomena, such as magnetic dichroism, and obtain the same information. Indeed, the similarity in the expression of the electron and x-ray c...
