Single-shot 3D coherent diffractive imaging of core-shell nanoparticles with elemental specificity. [PDF]

, 2018
We report 3D coherent diffractive imaging (CDI) of Au/Pd core-shell nanoparticles with 6.1 nm spatial resolution with elemental specificity. We measured single-shot diffraction patterns of the nanoparticles using intense x-ray free electron laser pulses.

Blocking Temperature of a System of Core/Shell Nanoparticles [PDF]

Solid State Phenomena, 2020
A theoretical study was made of the dependence of the blocking temperature of the core/shell system of nanoparticles on the intensity of their magnetostatic interaction. It is shown that with an increase in the concentration of nanoparticles (intensity of the magnetostatic interaction), the blocking temperature increases.
