The lanthanide-functionalized multifunctional hybrid nanoparticles combining the superparamagnetic core and the luminescent europium complex were successfully designed and assembled via layer-by-layer strategy in this work. It is noted that the hybrid nanoparticles were modified by a hydrophilic polymer polyethyleneimine (PEI) through hydrogen bonding which bestowed excellent hydrophilicity and...

Nanoscale hybrid magnets containing SmCo5 and Nd2Fe14B hard magnetic phases have been produced via a novel ‘‘in-one-pot’’ processing route. The grain size of the processed bulk composite materials is controlled below 20 nm. The refinement of the nanoscale morphology leads to effective inter-phase exchange coupling that results in single-phase like magnetic properties. Energy product of 14 MGOe ...

The rapid thermal processing (RTP) technique features dynamic control of temperature, which permits high heating and cooling rates that cannot be reached with conventional furnace treatments. In recent years, RTP has been increasingly applied to the processing of magnetic materials. The controllable heating profiles provide an approach for the deliberate construction of materials structure via ...
