Dynamics of 1D 3He adsorbed in 4He plated MCM-41: NMR Studies

ORAL

Abstract

We report the results of NMR studies of the dynamics of 3He confined to 1D in the interior of the hexagonal nanochannels of MCM-41. The walls of the MCM-41 were coated with a monolayer of 4He and 3He was added afterwards to form a 1D 3He line density of 0.1 Å-1. The nuclear spin-lattice relaxation times were measured for temperatures 0.050 < T < 3.0 K. A distinct peak is observed at 95 mK which is interpreted as the expected maximum of the “spin-drag” relaxation time predicted by theory for T = 2TF where TF is the Fermi degeneracy temperature.
