Local polar order in the ferroelectic-relaxor Na₁/₂Bi₁/₂TiO₃ as studied by ²³Na NMR
²³Na NMR spectra have been measured in a very low magnetic field at temperatures between 293 K and 729 K. The achieved spectral resolution is sufficient to test various models of short-range order in the Na₁/₂Bi₁/₂TiO₃ structure using computer simulations of the spectral line shape. The best agreeme...
