Abstract

The nuclear spin lattice relaxation time (T1) 7Li in the heavy fermion system LiV2O4 has been measured under high pressure up to 3.7 GPa. At ambient pressure, 1/T1 shows broad maximum around 50 K and is proportional to the temperature below 8 K. This is apparently quite similar to the relaxation behavior in f-electron systems. However, 1/T1 becomes larger with applying higher pressure below 10 K and does not obey T1T = constant relation down to 1 K. This pressure dependence of T1 is opposite to that of Ce compounds, such as CeCu5.9Au0.1 and CeCu2Si2. Spin dynamics of LiV2O4 under pressure is discussed.
