Phase structure control of Ni nanocrystals has been realized using a one‐pot chemical route. By adjusting the growth environment and growth dynamic process, pure cubic and hexagonal phase Ni nanocrystals can be obtained (see figure). Both the cubic and hexagonal phase Ni nanocrystals are shown to possess ferromagnetic properties, but the magnetic properties of the cubic phase are better than those of the hexagonal phase nanocrystals.
