superparamagnetic
Adjective
Meaning
superparamagnetic (comparative more superparamagnetic, superlative most superparamagnetic)
(physics) Of, pertaining to, or exhibiting superparamagnetism.
Examples
This explains why superparamagnetic nanoparticles have a much larger susceptibility than standard paramagnets: they behave exactly as a paramagnet with a huge magnetic moment.
In the former case, the nanoparticle will appear to be in the superparamagnetic state whereas in the latter case it will appear to be “blocked” in its initial state.
The state of the nanoparticle (superparamagnetic or blocked) depends on the measurement time.
Time dependence of the magnetization There is no time-dependence of the magnetization when the nanoparticles are either completely blocked ( ) or completely superparamagnetic ( ).
When an external magnetic field is applied to an assembly of superparamagnetic nanoparticles, their magnetic moments tend to align along the applied field, leading to a net magnetization.
