Paramagnetic Resonance of Metallobiomolecules
X-ray magnetic circular dichroism XMCD is the difference in absorption of leftand right-circularly polarized x-rays by a magnetized sample. Although MCD with x-rays is only about 15 years old, the physics is essentially the same as for UV-visible MCD that has been known since 1897. For (bio)inorganic chemists and materials scientists, XMCD has the advantage of elemental specificity that comes w...
متن کاملStrong K-edge magnetic circular dichroism observed in photon-in-photon-out spectroscopy.
A large enhancement of the x-ray magnetic circular dichroism is observed at the iron K absorption preedge of magnetite. This is achieved by performing resonant inelastic x-ray scattering (RIXS) experiments with a 2p hole in the final state of the second-order optical process. We measured and calculated the full 1s2p RIXS planes for opposite helicities of the incoming circularly polarized x rays...
متن کاملMagnetic 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.
متن کاملDomain wall propagation due to the synchronization with circularly polarized microwaves
Finding a new control parameter for magnetic domain wall DW motion in magnetic nanostructures is important in general and in particular for the spintronics applications. Here, we show that a circularly polarized magnetic field CPMF at gigahertz frequency microwave can efficiently drive a DW to propagate along a magnetic nanowire. Two motion modes are identified: rigid DW propagation at low freq...
متن کاملX-Ray Magnetic Absorption and Scattering (XMAS)
1 . Introduction Understanding of magnetic property and structure in magnetic materials forms a wide field of research interesting not only from a fundamental point but also from a practical point. Advantages in brilliance and polarization of 3rd generation synchrotron radiation (SR) open out a new field in magnetism differing from neutron magnetic scattering. In particular, this is characteriz...
