A novel diced spherical quartz analyzer for use in resonant inelastic X-ray scattering (RIXS) is introduced, achieving an unprecedented energy resolution of 10.53 meV at the IrL3absorption edge (11.215 keV). In this work the fabrication process and the characterization of the analyzer are presented, and an example of a RIXS spectrum of magnetic excitations in a Sr3Ir2O7sample is shown.

Increasing Temperature

Valence-band and Yb 4d photoemission spectra of YbXCu 4 (X=In, Cd, Mg) have been measured with high energy resolution from 10 to 300 K. In the valence-band photoemission spectra of YbInCu 4 and YbCdCu 4, the structure due to the Yb 2+ 4f 7/2 states is clearly observed near the Fermi level (E F ) at 10 K. The intensity of the Yb 2+ 4f 7/2 structure decreases with increasing temperature and the structure almost disappears at 300 K. The amount of the enhancement from 50 to 107 K is much stronger for YbInCu 4 than for YbCdCu 4. On the other hand, the Yb 2+ 4f 7/2 structure of YbMgCu 4 is observed as a broad peak near E F and the spectra show little temperature dependence. In the Yb 4d photoemission spectra of YbInCu 4 and YbCdCu 4, the structures due to the Yb 2+ and Yb 3+ states are recognized. The intensity ratio Yb 2+/ Yb 3+ increases with decreasing temperature. In the Yb 4d spectra of YbMgCu 4, on the other hand, almost only structures due to Yb 2+ states are observed.

And Performance

This article reports the development and characterization of a laboratory-based high-resolution X-ray powder diffractometer equipped with a 5.5 T magnet and closed-cycle helium cryostat that is primarily designed for the investigation of magneto-structural phase transitions. Unique features of the diffractometer include the position-sensitive detector, allowing the collection of an entire diffraction pattern at once, and the high energy resolution with Mo Kα 1 radiation. The ability to utilize a lower energy resolution but higher photon flux by switching to an X-ray mirror monochromator makes it a versatile setup for a variety of compounds. In this contribution, details of the design and performance of the instrument are presented along with its specifications.
