Abstract

See full text

A magnetic nanoparticle, and composites thereof, comprising a ternary host compound comprising a transition metal oxide of size 2-30 nm having two transition metal dopants atom incorporated therein, such that the nanoparticle is converted from superparamagnetic or weak ferromagnetic to strong ferromagnetic material. The strong permanent magnets are formed from non-rare earth materials. The composite material can also include undoped nanoparticles.
