Abstrakt: Single crystals of triglycine sulphate (TGS) doped with L-alanin, lysin and with Co.sup.2+.sup., Cd.sup.2+.sup. and PO.sub.4./sub..sup.3-.sup. were grown from aqueous solutions by means of slow cooling method. Concentration of doping elements varied from 5 to 20mol. per cent. Morphology, domain structure and P-E hysteresis loops have been investigated. TGS single crystals doped with Co.sup.2+.sup. and PO.sub.4./sub..sup.3-.sup. show the inernal fields as high as 217 kV/m with peculiarities in the hysteresis loops. The best hysteresis loop has been obtained on TGS crystal doped with Lysin and Cd.sup.2+.sup. ions.
