Magnetic nanocomposites (NCs) are extremely appealing for a wide range of energy-related
technological applications, specifically as building blocks for next-generation permanent …

In this review article, we focus on the relationship between permanent magnets and the
electric motor, as this relationship has not been covered in a review paper before. With the …

Exchange-coupled hard/soft ferrite nanoparticles are prospective to squeeze out a part of
expensive magnets based on rare earth elements. However, the known exchange-coupled …

Due to the issues associated with rare-earth elements, there arises a strong need for
magnets with properties between those of ferrites and rare-earth magnets that could …

Among hard/soft nanocomposites (NCs), ferrite-based materials are potentially promising for
developing exchange-coupled systems, thus leading to enhanced magnetic properties. In …

Featured Application Metallic nanoparticles with a high value of magnetization have
potential interest for application in biomedicine, catalysis, composite permanent magnets …

Sol–gel synthesis was used in order to obtain nanocrystallites of the SrFe 12 O 19 (SFO)
hexaferrite in an efficient and reliable way. By optimizing the initial synthetic conditions, we …

Strontium hexaferrite nanocrystalline powders were synthesized using a citrate combustion
method and subsequently subjected to post-synthesis processing with the aim of tuning the …

In the last few years, significant effort has again been devoted to ferrite-based permanent
magnet research due to the so-called rare-earth crisis. In particular, a quest to enhance …

CoFe2O4 nanoparticles (NPs) of∼ 5 nm have been synthesized by the polyol method and
subsequently used as seeds in a sol–gel process to prepare a ferrimagnetic …
