Description
Summary:The nuclear magnetization of 3He adsorbed by the nanostructured material MCM-41 with a channel size of 2.5 nm was investigated using the pulse nuclear magnetic resonance method. The amplitude of the spin-echo signal was measured in the experiment after the application of two probe pulses to the system. The resulting temperature dependence of the signal magnitude, for various 3He coatings, is described by common dependence corresponding to the Curie law. It is demonstrated that the values of the echo signal amplitude determined in the experiment coincide with the calculated value of the corresponding amplitude due to nuclear magnetization that arises in the system of 3He nuclear spins in an external magnetic field.
