High pressure on superparamagnetic nanoparticles for remanence and coercive force ?


For the single-domain size magnetic nano particles, they usually show
superparamagnetic properties.
I'm think whether it's possible to recover or re-creat remanence and
coercive force in the material by high pressure on the tiny dry
podwers inside some suitable case.
Is that possible? Anyone give me an answer ?

Thanks
