In this paper, the magnetization processes in cubic particles from initial saturation states are calculated by numerical micromagnetics. For particle sizes small than 800 Å, the remanent state has flowerlike magnetization configuration. Beyond 800 Å this state is replaced by a vortex structure. The angular dependence of the coercivity field is calculated for particle sizes of 400 Å, 600 Å, 700 Å, 750 Å, 800 Å, and 900 Å. For particle sizes small than 700 Å, they switch mostly in the coherent rotation. For particle sizes between 700 Å and 800 Å, the magnetization reversal process changes from coherent rotation to incoherent fanning. Beyond 800 Å, the magnetization reversal process is probably due to the wall motion.
