【 摘 要 】

We have synthesized (Pb_{1â€�?�ð�?��?}Sm_ð‘�?)(Sn_ð‘�?Ti_{1â€�?�ð�?��?})_{1â€�?�ð�?��?/4}O₃ (PSmST) polycrystalline ferroelectric ceramics with ð‘�? = 0.05, 0.07, 0.1 and ð‘�? = 0.45 by a solid-state reaction technique and performed preliminary X-ray diffraction (XRD) analysis, detailed temperature and frequency dependence dielectric measurements on them. The a.c. conductivity has been investigated over a wide range of temperature and the activation energy ($E_{a.c.}$) has also been calculated. It is observed that
