Absence of structural correlations of magnetic defects in heavy fermion LiV2O4

, 2008
Magnetic defects have pronounced effects on the magnetic properties of the face-centered cubic compound LiV2O4. The magnetic defects arise from crystal defects present within the normal spinel structure.

Crystal structure of AlFe0.95

IUCrData, 2023
Three B2-type intermetallic AlFe1 – δ phases (0.18 < δ < 0.05) in the Al–Fe binary system were synthesized by smelting and high temperature sintering methods. The exact crystal structure for δ = 0.05 was refined by single-crystal X-ray diffraction.

Characterization of Photonic Colloidal Single Crystals by Microradian X‐ray Diffraction [PDF]

Advanced Materials, 2006
Photonic crystals (PCs) can provide unprecedented control over both the emission and the propagation of light, allowing important applications in, for example, infrared telecommunications. [1–3] However, fabrication and characterization of PCs is challenging owing to the large refractive-index contrast that is needed to open up a photonic bandgap.

Crystal structure and phonon softening in Ca3Ir4Sn13

, 2015
We investigated the crystal structure and lattice excitations of the ternary intermetallic stannide Ca3Ir4Sn13 using neutron and x-ray scattering techniques. For T > T* ~ 38 K the x-ray diffraction data can be satisfactorily refined using the space group
