X-ray magneto-optics of lanthanide materials: principles and applications

X-ray magneto-optics of lanthanide materials: principles and applications

Lanthanide metals are a particular class of magnetic materials in which the magnetic moments are carried mainly by the localized electrons of the 4f shell. They are frequently found in technically relevant systems, to achieve, e.g., high magnetic anisotropy. Magnetooptical methods in the x-ray range are well suited to study complex magnetic materials in an element-specific way. In this work, we...

Optics for coherent X-ray applications

Developments of X-ray optics for full utilization of diffraction-limited storage rings (DLSRs) are presented. The expected performance of DLSRs is introduced using the design parameters of SPring-8 II. To develop optical elements applicable to manipulation of coherent X-rays, advanced technologies on precise processing and metrology were invented. With propagation-based coherent X-rays at the 1...

Magneto - Optics of freestanding Fe monolayers from first principles

The nonlinear magneto-optical Kerr-effect (NOLIMOKE) is determined for freestanding Fe monolayers with several in-plane structures from first principles. Based on the theory of nonlinear magneto-optics by Hübner and Benne-mann [Phys. Rev. B, 40, 5973 (1989)] we calculate the nonlinear susceptibil-ities of the monolayers using the ab initio FLAPW-method WIEN95 with the additional implementation ...

The effect of nurses' virtual learning on knowledge and practice of observing X-Ray protection principles

Background: Upgrading the level of staffs  knowledge in this regard can play an important role in reducing the complications of radiation in the community. Materials and Methods: This randomized clinical trial was coducted on 90 nurses.  To collect data, a demographic information form and a radiation protection and X-ray protective questionnaire and a performance checklist were used. Education...
