摘要: Multiferroic single crystals in the novel system Pb-Mn-Ni-Ti-O have been grown by the high temperature solution growth method. At room temperature the crystals are indexed in the hexagonal space group P6(3)cm. The dielectric and magnetic properties along with the temperature dependence of the c-lattice parameter have been studied in the temperature range 2 K - 500 ?. The magnetic measurements reveal a paramagnetic to antiferromagnetic phase transition around 48 K. The dielectric permittivity exhibits a maximum at 430 K, indicating ferroelectric to paraelectric phase transition. The temperature dependent Raman and XRD measurements around 430 K reveal an anomaly and abrupt change of the lattice parameter along the z-axis respectively, thus confirming the ferroelectric-to-paraelectric phase transition.
