Field Dependence of Blocking Temperature in Magnetite Nanoparticles
G. F. Goya, M. P. Morales
Spherical magnetite nanoparticles having average particle size <d> = 5 nm have been synthesized by coprecipitation of Fe(II) and Fe(III) salts in KOH with Polyvinylalcohol (PVA). T…
Magnetic properties and energy absorption of CoFe2O4 nanoparticles for magnetic hyperthermia
T. E. Torres, A. G. Roca, M. P. Morales +4
We have studied the magnetic and power absorption properties of three samples of CoFe2O4 nanoparticles with sizes from 5 to 12 nm prepared by thermal decomposition of Fe (acac)3 an…
Magnetic nanoparticles with bulk-like properties
Xavier Batlle, N. Pérez, P. Guardia +8
The magnetic behavior of nanoparticles synthesized either by high-temperature decomposition of an organic iron precursor or low-temperature co-precipitation in aqueou…
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…
