Magnetic Domains and Surface Effects in Hollow Maghemite Nanoparticles
Andreu Cabot, A. Paul Alivisatos, Victor F. Puntes +3
In the present work, we investigate the magnetic properties of ferrimagnetic and noninteracting maghemite (g-Fe2O3) hollow nanoparticles obtained by the Kirkendall effect. From the…
Surface anisotropy broadening of the energy barrier distribution in magnetic nanoparticles
Nicolas Perez, Pablo Guardia, Alejandro G. Roca +7
The effect of surface anisotropy on the distribution of energy barriers in magnetic fine particles of nanometer size is discussed within the framework of the scaling…
Particle size and cooling field dependence of exchange bias in core/shell magnetic nanoparticles
Oscar Iglesias, Xavier Batlle, Amilcar Labarta
We present a numerical simulation study of the exchange bias (EB) effect in nanoparticles with core/shell structure aimed to unveil the microscopic origin of some of the experiment…
