- Abstract
MCM-41 is a unique mesoporous material with cylindrical-like pores that provide an ideal platform to study 1D properties of adsorbed atoms (Boninsegni and Moroni in J Low Temp Phys 118(1):1, 2000). In this research, we use pulsed NMR to measure the nuclear spin-lattice relaxation times ( T 1 ) of 3 He adsorbed onto 4 He-preplated MCM-41 over a wide range of temperatures for a line density that would lead to a Fermi temperature of 200 mK. The temperature dependence of the nuclear spin-lattice relaxation time for 0.025 < T < 3.5 K exhibited a pronounced peak at 195 mK, qualitatively similar to that calculated for the spin relaxation of 1D Fermi systems.
