要約

The role of magnetically structural anisotropy of superparamagnetic nanoparticle clusters in hyperthermia heating was investigated based on discussion of magnetic hysteresis of clusters with 3D simple cubic lattice through Monte Carlo simulations. For the first time, a parameter was introduced to quantitatively evaluate the magnetically structural anisotropy of cluster along field axis. It was found that the heating efficiency increases with increasing magnetically structural anisotropy of the cluster along field axis, which can be intensified by increasing morphology anisotropy along the field axis, i.e. forming chain or cylinder. The potential of morphology-anisotropy-less clusters cannot be underestimated because they are relatively competitive in the evaluation of collective magnetically structural anisotropy of full-range angle between axes of morphology anisotropy and magnetic field as well as mature preparation technology.
