N2 - NMR studies were carried out on three isotopes, Ga-71, Ga-69, and In-115, in liquid gallium-indium (Ga-In) alloy embedded into glasses with 200 and 5 nm pore sizes at two magnetic fields, 9.4 and 17.6 T. Spin-lattice relaxation and the Knight shift were found to depend on pore size. For porous glass with 5 nm pores the relaxation rate was field-dependent which evidenced that the extreme narrowing limit was no longer valid. Magnetization recovery data were used to evaluate the correlation times of atomic mobility and the quadrupole constants under nonoconfinement. (C) 2012 Elsevier B.V. All rights reserved.
