Superparamagnetism
TkVK Bparticleani
Superparamagnetic limit: time and thermal stability
Correlate the electronic, magnetic and structural properties with the size, aspect ratio, crystalline structure, and chemical composition of each individual particle.
The ability to manipulate a single nanoparticle has an increased potential in device manufacturing
Ensembles vs Single-Particle Properties
Ensembles:
Distributions with respect to nanoparticle size, aspect ratio crystalline structure, defect distribution and chemical composition
