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 …

Permanent magnets (PMs) have tremendous demand because of their applicability in
various electronic devices. Rare earth (RE) elements are the major component in fabricating …

Ion substitution is considered to be one of the efficient approaches to improve the magnetic
properties of the barium hexaferrites. In this work, we fabricated BaFe 12− x Al x O 19 (x= 0 …

Ferromagnetic ferrofluids are synthetic materials consisting of magnetic nanoplatelets
dispersed in an isotropic fluid. Their main characteristics are the formation of stable …

Powders of BaFe 12 O 19 and SrFe 12 O 19 ferrites are synthesized by hydrothermal
method from iron, strontium, and barium nitrates. The ratio of iron and barium (strontium) …

Magneto-mechanical actuation (MMA) using the low-frequency alternating magnetic fields
(AMFs) of magnetic nanoparticles internalized into cancer cells can be used to irreparably …

The hard ferrites called hexaferrites or hexagonal ferrites show excellent characteristics
which makes them suitable for many potential applications. The magnetic characteristics of …

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 …

Barium hexaferrite nanoplatelets (BHF NPLs) are permanent nanomagnets with the
magnetic easy axis aligned perpendicular to their basal plane. By combining this specific …

Understanding the processes involved in the formation of nanoparticles is a prerequisite for
the control of their morphology. In this investigation we reveal the processes leading to the …
