Description
Summary:S Crystals of Pb sub(3)Ni sub(1.5)Mn sub( 5.5)O sub(15) were successfully grown by the high temperature solution growth method. Their composition was determined by energy dispersive X-ray analysis. The phase homogeneity of the grown crystals was examined and confirmed by powder X-ray phase analysis. The structure was characterized by X-ray single crystal diffractometry and was indexed in the trigonal space group P-3c1 (No. 165) with lattice parameters a = 9.9142(2) [Angstrom] and c = 13.4923(18) [Angstrom]. The dielectric properties of Pb sub(3)Ni sub(1.4)Mn sub( 5.6)O sub(15) were investigated in the temperature range 150 - 500 K. The AC -measurements were carried out for 3 different frequencies: 10 kHz, 100 kHz and 1 MHz. From the DC measurements thermal activation energy was estimated.
