| 中文摘要 | The dipole-dipole interactions of monodisperse Fe(3)O(4) nanoparticles (NPs) can be directly controlled by a uniform SiO(2) shell with different thickness, i.e., different interspacings. Thus, the interacting strength of a serial of Fe(3)O(4)-SiO(2) NPs system can be revealed by fitting the blocking temperature TB measured at ac fields to the Vogel-Fulcher law. The interspacing over five times of diameter for less than 8.0 nm Fe(3)O(4) NPs is the critical value to achieve a noninteracting system. Furthermore, a general equation to evaluate critical interspacing for noninteracting magnetic NPs systems with different sizes and saturation magnetizations was calculated by Monte Carlo method.
