Superstructures in iron-based superconductor Cs0.8Fe1.6Se2
Cs0.8Fe1.6Se2 becomes superconducting below 27K despite the presence of antiferromagnetism with a large moment of about 3.3 Bohr magnetons and an unusually high ordering... -
Diffuse scattering in the paraelectric phase of titanite
Titanite consists of TiO6 octahedra arranged in chains. These are linked by SiO4 tetrahedra. At room temperature, Ti is slightly off-center resulting in an alternation of short...
