The polarization switching in methylammonium chlorobismuthate, (CH 3 NH 3 ) 5 Bi 2 Cl 11 , single crystal was investigated by optical observations of the domain structure and switching current registration. It is shown that defects introduced during crystal growth influence the polarization switchin

A T1 minimum at 216 K for Larmor frequency 90 MHz has been detected and for this minimum no analogous T, minimum according to the known quadratic dependence of the Larmor frequency 25 MHz is found. The analysis leads to the conclusion that this T1 minimum is a result of the relaxation of protons via
Raman spectra of (DMAPCC) single crystals were studied over the range 10-3200 cm-1 Cl 11 between 100 and 360 K. The changes in the external and internal mode region were observed and characterized. In particular, the symmetric stretching vibration of the dimethylammonium (DMA) group at 890 cm-1 spl
