Domain Size of Phase-Separated NaxCoO2 as Investigated by X-Ray Microdiffraction
O3-NaCoO2 is a promising cathode material for sodium ion secondary batteries (SIBs). NaxCoO2 shows phase separation (PS) into the O3 and O′3 phases in the Na concentration range of 0.89 6 x 6 0.99. In order to estimate the domain size (r) in the two-phase region, we performed X-ray microdiffraction (XRMD) of thin films of NaxCoO2 at x = 0.97 and ∼1. We found that r (≈400 nm) of the O′3 domain i...
متن کاملMagnetic x-ray microdiffraction
Magnetic x-ray microdiffraction uses the structural specificity of x-ray diffraction to probe complex magnetic structures at the length scales relevant to physical phenomena including domain dynamics and phase transitions. Conventional magnetic crystallography techniques such as neutron or x-ray diffraction lack this spatial resolution. The combination of both reciprocal space and real space re...
متن کاملX-ray microdiffraction images of antiferromagnetic domain evolution in chromium.
Magnetic x-ray diffraction combined with x-ray focusing optics was used to image individual antiferromagnetic spin density wave domains in a chromium single crystal at the micron scale. The cross section for nonresonant magnetic x-ray scattering depends on the antiferromagnetic modulation vector and spin polarization direction and allows these quantities to be extracted independently. The techn...
متن کاملLawrence Bragg, microdiffraction and X-ray lasers.
We trace the historical development of W. L. Bragg's `law' and the key experimental observation which made it possible using polychromatic radiation at a time when neither X-ray wavelengths nor cell constants were known. This led, through his phasing and solving large mineral structures (without use of a computer), to work on metals, proteins, bubble rafts and his X-ray microscope. The relation...
متن کاملPolycapillary X-ray optics for microdiffraction
Polycapillary optics, i.e. shaped arrays consisting of hundreds of thousands of hollow glass capillary tubes, can be used to redirect, collimate or focus X-ray beams. X-rays emitted over a large angular range from conventional laboratory-based sources can be transformed into a beam with a small angular divergence or focused onto a small sample or sample area. Convergent beams of X-rays, with co...
