'Lithium diffusion in lithium nitride by Pulsed-Field Gradient NMR'
, Phys. Chem. Chem. Phys. 14 13535-13538 (2012) doi:

Lithium self-diffusion coefficients are measured for the first time using 7Li Pulsed-Field Gradient Nuclear Magnetic Resonance (PFG-NMR) in a crystalline inorganic solid-state powder of α-Li3N between 534 K and 774 K. The diffusion of lithium cations is anisotropic, and the activation energy for the diffusion within the Li2N layers is about 0.15 eV.
