abstract = {This contribution addresses the experimental proof of the
relaxation coupling of the 7Li (I = 3/2) longitudinal
magnetization orders in the solid-state electrolyte
Li10GeP2S12 (LGPS). This effect was theoretically described
by Korb and Petit in 1988 but has not yet been shown
experimentally. In a 2D-T1/spin-alignment echo (SAE)
experiment, the inverse Laplace transformation of the
spectral component over two time dimensions revealed the
asymmetric course of the spin-lattice relaxation following
from the coupling of all longitudinal orders. These
observations were supported by Multi-quantum-filter
experiments and by simulations of the 2D-T1/SAE experiment
with a lithium spin system. Since the asymmetric relaxation
effects are directly dependent on the velocities and degrees
of freedom of ion motion they could be used especially in
fast Li-ion conductors as a separation tool for environments
with different mobility processes.},
