abstract = {The mobility of Na+ ions in Na3+xSc2(SiO4)x(PO4)3−x (0.1
< x < 0.8) was investigated by temperature-dependent 23Na
NMR spectroscopy and relaxometry. These measurements are
probing the local motion of the Na+ ions and give
information about the average hopping rate of the ions and
the activation barriers these ions have to overcome for
single jumps. The results are compared with those obtained
by impedance spectroscopy that is probing the long-range
transport of the Na+ ions. A consistent picture is obtained
with the fastest motion of the Na+ ions observed for the
sample with x = 0.4.},
