Sb nuclear spin-lattice relaxation rate in filled skutterudite superconductor PrOs4Sb12

nuclear spin-lattice relaxation rate has been measured for the filled skutterudite superconductor PrOs4Sb12 with in order to probe the multipole fluctuations. Within the conventional analyses for NMR relaxation process, we found that 1/T1 for is suppressed by magnetic fields. However, the ratio of t...

Description
Summary:nuclear spin-lattice relaxation rate has been measured for the filled skutterudite superconductor PrOs4Sb12 with in order to probe the multipole fluctuations. Within the conventional analyses for NMR relaxation process, we found that 1/T1 for is suppressed by magnetic fields. However, the ratio of to 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.
