Magnetic Interactions and Energy Barrier Enhancement in Core/Shell Bimagnetic Nanoparticles
(American Chemical Society, 2015-07)
In this work, we studied the dynamic and static magnetic properties of ZnO-core/CoFe2O4-shell and CoO-core/CoFe2O4-shell nanoparticles. Both systems are formed by a core of ∼4 nm of diameter encapsulated in a shell of ∼2 ...
Controlling the dominant magnetic relaxation mechanisms for magnetic hyperthermia in bimagnetic core-shell nanoparticles
(Royal Society of Chemistry, 2019-02)
We report a simple and effective way to control the heat generation of a magnetic colloid under alternate magnetic fields by changing the shell composition of bimagnetic core–shell Fe3O4/ZnxCo1−xFe2O4 nanoparticles. The ...
Impact of core-shell dipolar interaction on magnetic phases of spherical core-shell nanoparticles
(American Physical Society, 2015-08-26)
Structural and magnetic properties of nanoparticles of La2/3Sr1/3MnO3
(Elsevier, 2006-10-01)
Nanoparticles of the manganite were synthesized using the Pechini process and their structural properties were characterized by X-ray diffraction (XRD) and by transmission electron microscopy (TEM). The magnetization of ...
Magnetic nanoparticles: Co@SiO2, Co@Au and Co@Pt
(2011-01-01)
Nanotechnology is the understanding and control f matter at dimensions of roughly 1 - 100 nm. At the nanoscale, the properties like electrical conductivity and mechanical strength are not the same as the materials with ...
Biocompatible Magnetic Microspheres for Use in PDT and Hyperthermia
(AMER SCIENTIFIC PUBLISHERSVALENCIA, 2012)
Loaded microspheres with a silicon (IV) phthalocyanine derivative (NzPC) acting as a photosensitizer were prepared from polyhydroxybutyrate-co-valerate (PHBHV) and poly(ecaprolactone) (PCL) polymers using the emulsification ...
A simple method to obtain Fe-doped CeO2 nanocrystals at room temperature
(Elsevier Science BvAmsterdamHolanda, 2013)
Observation of ferromagnetism in PdCo alloy nanoparticles encapsulated in carbon nanotubes
(Amer Inst PhysicsMelvilleEUA, 2010)
Surface spin disorder effects in magnetite and poly(thiophene)-coated magnetite nanoparticles
(Amer Inst PhysicsMelvilleEUA, 2010)
Phosphate glasses containing monodisperse Fe3−δO4@SiO2 stellate nanoparticles obtained by melt-quenching process
(2020-06-01)
The challenge to obtain stable glasses containing monodisperse magnetic nanoparticles with controlled size and shape is an exciting and almost unexplored field of research. Such new materials can be used in magneto-photonics ...
