Abstract

Provided herein are systems, methods, and compositions for magnetic nanoparticles and bulk nanocomposite magnets.

First claim

What is claimed is:

1. A process of forming a plurality of magnetic nanoparticles comprising:
a. providing a powder with particles of a first size in an inert environment;
b. dissolving the powder in a first solvent with a surfactant;
c. ball milling the powder into a plurality of nanoparticles having a second size;
d. dispersing the nanoparticles into a second solvent; and
e. separating the nanoparticles by a size selection process.

2. The process of…
