Magnetic nanoparticles (MNPs) are of great scientific interest because of the size effect
associated with their magnetic properties and, even more so, because of their wide-ranging …

Permanent magnets based on hard hexaferrite represent the largest family of magnets being
used today by volume. They generate moderate remanence induction, but present crucial …

The barium hexaferrite, BaFe12O19, microcrystals were obtained by the flux crystal growth
method and were characterized by XRD, SEM, and TEM methods. XPS measurements were …

Yttrium iron garnet ferrite (YIG), with good magnetic and dielectric properties, was mixed with
doped magnesium spinel ferrite (Y 3 Fe 5 O 12 (x)/Mg 0.4 Cd 0.4 Co 0.2 Fe 2 O 4 (1-x)(x …

Exchange coupling magnetic composites have been proven to help improve the microwave
absorption performance of absorbents. However, composite systems reported showed …

We have investigated the bottom-up sol-gel synthesis of nanocomposite powders
comprising two magnetic phases (hexagonal Sr ferrite and spinel Co ferrite) in order to …

Net-shaped hexagonal barium and strontium ferrites with desirable shapes have been
successfully fabricated by the extrusion-based three-dimensional (3D) printing. The …

In this contribution, hierarchical CoFe2O4 particles are successfully prepared via a modified
polyol elaboration method with NaBH4 and a proposed heat treatment process. Here, new …

The magnetic coupling of a set of SrFe12O19/CoFe2O4 nanocomposites is investigated.
Advanced electron microscopy evidences the structural coherence and texture at the …

In this investigation we analyze an unprecedented difference in the behavior of
nanoparticles when compared to the corresponding bulk. We have found that a chemical …
