Description

Sb121,123 nuclear spin-lattice relaxation rate (1/T1)121,123 has been measured for the filled skutterudite superconductor PrOs4Sb12 with Tc=1.85K in order to probe the multipole fluctuations. Within the conventional analyses for NMR relaxation process, we found that 1/T1 for H parallel [001] is suppressed by magnetic fields. However, the ratio of (1/T1)121 to (1/T1)123 is close to 3.4, implying that the magnetic relaxation process is dominant under the magnetic field. These results cannot be explained by a simple magnetic relaxation mechanism due to the spin-dipolar relaxation process
