Chains of Superparamagnetic Nanoparticles

Molecularly linked γ‐Fe2O3 nanoparticles chains are produced from superparamagnetic γ‐Fe2O3 nanoparticles under zero applied magnetic field. The chains exhibit ferromagnetic interaction between γ‐Fe2O3 nanoparticles that compose them as evidenced by an increase in blocking temperature from ∼80 K in...

Zusammenfassung:Molecularly linked γ‐Fe2O3 nanoparticles chains are produced from superparamagnetic γ‐Fe2O3 nanoparticles under zero applied magnetic field. The chains exhibit ferromagnetic interaction between γ‐Fe2O3 nanoparticles that compose them as evidenced by an increase in blocking temperature from ∼80 K in the case of isolated nanoparticles to ∼120 K for chains.
