Soft X-ray resonant magnetic diffraction.
We have conducted the first soft x-ray diffraction experiments from a bulk single crystal, studying the bilayer manganite La2-2xSr1+2xMn2O7 with x=0.475 in which we were able to access the (002) Bragg reflection using soft x rays. The Bragg reflection displays a strong resonant enhancement at the L(III) and L(II) manganese absorption edges. We demonstrate that the resonant enhancement of the ma...
متن کاملThe Local Ordering of Molten LiNbOa by X-ray Diffraction
LiNbO a crystal has excellent electro-optical and non-linear optical properties [1, 2]. However local fluctuations of the refractive index and light scattering centers prevent a wider application of this material in optical devices. Since sub-grain boundaries seem to cause such inconvenience, the production of sub-grain free LiNbO a crystals is strongly required. Various properties of molten L ...
متن کاملResonant soft X-ray diffraction - in extremis.
The use of softer-energy X-rays produced by synchrotron radiation for diffraction is an area of current interest. In this paper, experiments exploiting resonant scattering at the L absorption edges of 3d transition metal elements are reported. Such energies, typically 500-1000 eV, are at the extreme limit of soft X-ray diffraction where absorption effects are so severe that the sample and diffr...
متن کاملResonant X-ray Diffraction: basic theoretical principles
We present the main steps governing the theory of resonant x-ray diffraction (RXD). We focus on the derivation of the anomalous scattering amplitude from perturbation theory and starting from the low-energy expansion of the Dirac Hamiltonian. We give the main ingredients of the multipolar expansion in term of electric and magnetic transitions. We also show the expansion in terms of scattering t...
متن کاملX-ray Analysis of Magnetic Multilayers
Combined methods of X-ray reflectivity and X-ray diffraction were used in a structural study of Ag/NiFe multilayers with different thickness of the magnetic sublayer and during an annealing process. The results explain from the microscopic point of view distinctions found in their magnetic behavior. The XRD methods used are based on the distorted-wave Born approximation theory in the region clo...
