摘要

磁悬浮液在磁场中凝固可产生一种铁复合材料，其特征是沿着纳米粒子的易磁化轴产生取向纹理。在修正的平均场理论框架内，考虑到粒子间的磁偶极子相互作用，计算出了这种纹理的特征。蒙特卡罗计算机模拟数据证实了理论预测。

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.
