We report the temperature and field dependence of dc magnetization on sol-gel prepared nanoparticles of Ni(OH)2. At higher temperature the system is found to behave as a paramagnet while we find evidence for superparamagnetic blocking at low temperature. The system shows a paramagnet-superparamagnet transition and we discuss the underlying mechanism.
