A typical crossover behavior is found for the correlation effect on $\\chi_{\\rm{VV}}$ as sweeping spin-orbit interaction, $\\lambda$. For a small $\\lambda$, orbital fluctuation plays a dominant role in the correlation enhancement of $\\chi_{\\rm{VV}}$; however, the enhancement rate is rather small. In contrast, for an intermediate $\\lambda$, $\\chi_{\\rm{VV}}$ shows a substantial increase, accompanied by the development of spin fluctuation.
