Glassy Dielectric Response in Tb_2NiMnO_6 Double Perovskite with Similarities to a Griffiths Phase

Hariharan Nhalil, Harikrishnan. S. Nair, H. L. Bhat +1

Frequency-dependent and temperature-dependent dielectric measurements are performed on double perovskite Tb${}_2$NiMnO${}_6$. The real (${\epsilon }_1$) and imaginary (${\epsilon }_2$) parts of dielectric…
