Crystal structure and enhanced microwave dielectric properties of the Ce2[Zr1−x (Al1/2Ta1/2) x ]3(MoO4)9 ceramics at microwave frequency

Journal of Advanced Ceramics, 2022
Dense microwave dielectric ceramics of Ce2[Zr1 − x (Al1/2Ta1/2) x ]3(MoO4)9 (CZMAT) (x = 0.02–0.10) were prepared by the conventional solid-state route. The effects of (Al1/2Ta1/2)4+ on their microstructures, sintering behaviors, and microwave dielectric

An x-ray resonant diffraction study of multiferroic DyMn2O5

, 2007
X-ray resonant scattering has been used to measure the magnetic order of the Dy ions below 40K in multiferroic DyMn$_{2}$O$_{5}$. The magnetic order has a complex behaviour. There are several different ordering wavevectors, both incommensurate and commensurate, as the temperature is varied.

X-Ray Standing Wave in Resonant Dynamical Diffraction.

Nihon Kessho Gakkaishi, 2000
X-ray standing wave method is widely used for determination of atomic position of an adsorbate at surface, an impurity atom in a bulk or an atom at an interface. If the method is combined with X-ray resonant scattering, novel applications are expected as the resonant scattering occurs in a very narrow region of X-ray energy, and the scattering factor ...

Direct Phasing of Finite Crystals Illuminated with a Free-Electron Laser

Physical Review X, 2015
It has been suggested that the extended intensity profiles surrounding Bragg reflections that arise when a series of finite crystals of varying size and shape are illuminated by the intense, coherent illumination of an x-ray free-electron laser may ...

Tuning chirality amplitude at ultrafast timescales in chiral CsCuCl_{3}

Physical Review Research
Chirality is a fundamental symmetry concept relevant to many scientific fields. It describes discrete states, i.e., left-handed, right-handed, or achiral. In contrast to this discrete classification, objects can be continuously distorted. To describe the

Magnetic resonant x-ray diffraction study of europium telluride

Physical Review B, 2008
Here we use magnetic resonant x-ray diffraction to study the magnetic order in a $1.5\text{ }\ensuremath{\mu}\text{m}$ EuTe film grown on (111) ${\text{BaF}}_{2}$ by molecular-beam epitaxy. At $\text{Eu}\text{ }{L}_{\text{II}}$ and ${L}_{\text{III}}$ absorption edges, a resonant enhancement of more than two orders was observed for the $\ensuremath ...

Cu–Mo Thin Film Electrodeposited at a Rate of Megahertz by a Rectangular Pulse Current Technique

International Journal of Electrochemical Science, 2017
Cu-Mo thin films generated on ITO glasses by a rectangular pulse current technique having a frequency of megahertz were investigated using energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and scanning electron microscope (SEM).
