Ferroelectric phase transition in Ba5RTi3Nb7O30 [R=Nd, Eu, Gd] ceramics
- 1. Dept. of Physics, Indian Institute of Technology, Kharagpur (India)
Description
Polycrystalline samples of Ba5RTi3Nb7O30[R = Nd, Eu, Gd], were prepared using high-temperature solid-state reaction technique. Preliminary x-ray structural analysis of the compounds shows the formation of single phase compounds (orthorhombic crystal system) at room temperature. Detailed studies of dielectric properties (ε, tan δ, ω) as a function of frequency (400 Hz to 10 kHz) and temperature (30 deg to 380 degC) show that these compounds exhibit diffuse ferroelectric phase transition.
