Modelling exchange bias in core/shell nanoparticles [PDF]
Journal of Physics: Condensed Matter, 2007 We present an atomistic model of a single nanoparticle with core/shell structure that takes into account its lattice strucutre and spherical geometry, and in which the values of microscopic parameters such as anisotropy and exchange constants can be ...

Core‐passivation: A concept for stable core‐shell nanoparticles in aqueous electrocatalysis
Nano Select, 2023 The stability of nanoparticles is a major challenge in thermal and electrocatalysis. This is especially true for core‐shell nanoparticles where only a few monolayers of noble metal protect the usually non‐noble core material. In this work, we utilize the

Tailoring topological states of core–shell nanoparticles [PDF]
Physica E: Low-dimensional Systems and Nanostructures, 2022 In this work we investigate novel spherical core-shell nanoparticles with band inversion. The core and the embedding medium are normal semiconductors while the shell material is assumed to be a topological insulator. The envelope functions are found to satisfy a Dirac-like equation that can be solved in a closed form.

Magnetic−Plasmonic Core−Shell Nanoparticles [PDF]
ACS Nano, 2009 Nanoparticles composed of magnetic cores with continuous Au shell layers simultaneously possess both magnetic and plasmonic properties. Faceted and tetracubic nanocrystals consisting of wustite with magnetite-rich corners and edges retain magnetic properties when coated with a Au shell layer, with the composite nanostructures showing ferrimagnetic ...
