The determination of induced mechanical forces in ball mills is an ongoing problem, which is so far mainly addressed by simulations. Herein, we suggest utilizing superparamagnetic microballoons as sensor particles for mechanical stress. The defined assembly of superparamagnetic nanoparticles yields microballoons with hollow cores, which makes them susceptible to mechanical forces. It is .
In this study, cobalt ferrite (CoFe2O4) nanoparticles were synthesized by intensive mechanical alloying of CoCO3 and αFe2O3 powder using a planetary high energy ball mill in air without any subsequent heat treatment. Effects of milling time on the phase composition, morphology and magnetic properties of the powders were evaluated using XRD, FESEM and VSM techniques, respectively.

A nanoparticle or ultrafine particle is usually defined as a particle of matter that is between 1 and 100 nanometres (nm) in diameter. The term is sometimes used for larger particles, up to 500 nm, [citation needed] or fibers and tubes that are less than 100 nm in only two directions. At the lowest range, metal particles smaller than 1 nm are usually called atom clusters instead.
