The NMR and IR spectra of (NH 4) 2SO 4 and (NH 4) 2BeF 4 have been investigated both in the non-ferroelectric and in the ferroelectric phases. From the measured second moments it was found that at room temperature the reorientations of the NH 4 + ions do not remain correlated with...
The EPR and pulsed NMR measurements of (NH4)2ZnBr4:Mn2+ have been carried out in the temperature range 110-473 K and 83-284 K, respectively. EPR spectra from three different paramagnetic entities have been observed. Intensity changes of certain lines in the EPR spectrum observed at 430 K ...
NMR ( 19 F, 1 H) methods are used to study ionic mobility in heptafluorozirconate (NH 4 ) 2.4 Rb 0.6 ZrF 7 in a range of temperatures from 150 K to 430 K. Types of ionic movements are determined, and their activation energy is evaluated. As a result of a phase transition a modi...
