Phase transition and polar cluster behavior above Curie temperature in ferroelectric BaTi${}_{0.8}$Zr${}_{0.2}$O${}_3$

Oktay Aktas, Francisco Javier Romero, Zhengwang He +5

We study the phase transition behavior of the ferroelectric BaTi${}_{0.8}$Zr${}_{0.2}$O${}_3$ in the paraelectric region. The temperature dependencies of thermal, polar, elastic and diel…
