Observation of magnetic circular dichroism in FeL2,3x-ray-fluorescence spectra

Magnetic circular dichroism in the soft-x-ray absorption spectra of Mn-based magnetic intermetallic compounds

We have investigated the magnetic electronic structures of PtMnSb, NiMnSb, Ni2MnSb,MnSb, MnAlGe, and Mn2Sb by soft-x-ray absorption spectroscopy ~XAS! and magnetic circular dichroism ~MCD! measurements in the Mn 2p core absorption region. Different degrees of the electron itinerancy of the Mn 3d states are discussed. The large orbital angular momentum of the Mn 3d electrons is revealed for MnSb...

The role of the spin polarization in x-ray magnetic circular dichroism spectra of itinerant magnets

Applications of x-ray magnetic circular and linear dichroism (XMCD and XMLD) are reviewed in the soft x-ray region, covering the photon energy range 0.4-2 keV, which includes important absorption edges such as the 3d transition metal L2,3 and rare earth M4,5. These techniques enable a broad range of novel and exciting studies such as on the electronic properties and magnetic ordering of novel n...

Unexpected Film Thickness Effect in Magnetic Circular Dichroism Spectra

Magnetic circular dichroism in the L2,3 x-ray fluorescence of Fe and Co

the L2,3 x-ray fluorescence spectra of magnetized Fe and CO excited by circularly polarized synchrotron radiation exhibit magnetic circular dichroism. The results are compared to the energy resolved spin polarized densities of states given by first-principles calculations.

Fluorescence-detected magnetic circular dichroism of fluorescent and nonfluorescent molecules.

We have modified a spectrometer for the measurement of fluorescence-detected magnetic (and natural) circular dichroism (FDMCD). The instrument can be operated either in a direct mode in which the average and polarization-induced differential fluorescent intensities are recorded separately or in a mode which records their ratio. We have measured the FDMCD of tryptophan, which is itself fluoresce...
