![]() | Ailion, David Charles | 93Nb NMR in the imcommensurate and quasi-commensurate phases of barium sodium niobate | NMR spectra have been measured for the quadrupole perturbed 1/2 -1/2 transition of 9 3Nb in barium sodium niobate (BSN) between 300 and 650 K. The spectra are inhomogeneously broadened in the incommensurate (/) phase between T7 = 580 K and r c = 540 K as well as in the quasicommensurate (QC) phase ... | NMR; Spectra; Barium sodium niobate; Line shapes | 1994 |
