N2 - In order to investigate the evolution of magnetic properties when the ground state changes from magnetism to superconductivity, we have performed In-NQR measurements under hydrostatic pressure in heavy-fermion antiferromagnetic compound, CeIn3. Peaks in the In-NQR spectra were shifted in the magnetically ordered state due to the appearance of the asymmetric parameter η, which enables us to determine the ordering temperature TN, precisely. TN in our measurement is in good agreement with that from the resistivity measurement. Nuclear spin-lattice relaxation rate 1/T1 increases gradually upon cooling in the paramagnetic state at pressure (P) smaller than 15 kbar, whereas 1/T1 shows slightly decreasing behavior with decreasing T above TN at P>15 kbar. It is suggested that the magnetic property at TN may change from the localized to itinerant regime around 15 kbar, above which the Kondo temperature TK is higher than TN.
