Texturing of the Easy Axes of Magnetic Nanoparticles during Freezing of a Magnetic Suspension in the Presence of an External Field

Solidification of a magnetic suspension in the presence of a magnetic field can produce a ferrocomposite characterized by an orientation texture along the easy magnetization axes of nanoparticles. The characteristics of this texture were calculated taking into account the interparticle magnetic–dipole interaction within the framework of a modified mean field theory. Theoretical predictions were confirmed by Monte Carlo computer simulation data.
