Abstract
La based Co–Fe combined double perovskite (La1.8Pr0.2CoFeO6) was synthesized and the dielectric (zero-field and in-field), magnetic, x-ray absorption and Raman spectroscopy measurements have been investigated for La1.8Pr0.2CoFeO6 double perovskite. The existence of re-entrant cluster glass state is observed. The magneto–dielectric (MD) is found in two temperature regions (25–80 K and 125–275 K). It has been demonstrated that the observed MD at low and high temperatures are respectively due to the spin freezing and the spin–lattice coupling. Furthermore, the very large dielectric constant and the low loss suggest that La1.8Pr0.2CoFeO6 is very important from the application point of view.
