Abstract

Layered perovskite structured Re₅Ti₄CrO₁₇ (Re = La, Nd) ceramics were synthesized via a sol–gel method. Rietveld analysis and Raman spectroscopy showed that the samples crystallize into an orthorhombic crystal structure with the space group Pmnn. The samples showed a dense and homogeneous microstructure when sintered at 1600 °C for 4 h and the grain size was found to be 2.64–4.93 μm. La₅Ti₄CrO₁₇ and Nd₅Ti₄CrO₁₇ exhibited dielectric constant (ε_r) ~ 23 and 12 at 1 MHz, respectively, which was dependent on the dielectric polarizability and bond lengths. Dielectric loss at room temperature was found to be ≤ 0.05 (at 1 MHz) for La₅Ti₄CrO₁₇ and Nd₅Ti₄CrO₁₇, respectively. Furthermore, magnetic study of the samples showed a paramagnetic behavior.
