Special Issue Information

Dear Colleagues,

Soft magnetic materials have been used widely for almost one century. These materials can be farbricated into various high-performance devices owing to their low coercivity and high saturation magnetization and permeability. Recently, novel soft magnetic materials have been used to develop innovative devices with low loss and small size using cutting-edge micro-nano technology. This Special Issue focuses on recent developments in magnetic soft materials, focusing micro- and nano-structure aspects, including their synthesis, characterization, and applications.

Contributions focusing on the topic from different perspectives are welcome. The aim of this Special Issue is to share the most recent novel findings on the growth and development of soft magnetic materials for micro-nano-systems and innovative devices, including areas of magnetic micro/nano-particles, ferrofluids, magnetic-resonance imaging, magnetic filtering, magnetic sensors, magnetic actuators, biomedical applications, etc.

Abstract

Magnetite nanoparticles and clusters of nanoparticles have been of Increasing scientific interest in the past decades. In order to prepare nanoparticles and clusters that are stable in suspension, different coatings have been used. Phosphates and phosphonates are a preferred anchoring group for the coating of magnetite nanomaterials. However, poly(vinylphosphonates) have rarely been used as a coating agent for any nanoparticles. Here, poly(methylvinylphosphonate) and other substituted polyvinylphosphonates are described as new coatings for magnetite nanoparticles and clusters. They show great stability in aqueous suspension. This is also the first time phosphonate-coated magnetite clusters have been synthesized in a one-pot polyol reaction. The coated magnetite nanoparticles and clusters have been characterized by TEM, EDX, FTIR, magnetization measurement, XRD as well as XPS. It has been shown that substituted vinylphosphonates can be easily synthesized in one-step procedures and as a polymeric coating can imbue important properties such as stability in suspension, tight binding to the particle surface, the ability to be further functionalized or to tightly adsorb metal ions. For the synthesis of magnetite clusters the cluster formation, polymerization and coating are done in a one-pot reaction and the resulting magnetite clusters show a higher amount of phosphonate coating than with a three-step procedure including a ligand exchange.
