Spectroscopic and electrical properties of Mg–Ti ferrite doped with different rare-earth elements

The dielectric constant ( ε′), and the electric conductivity ( σ) for Mg 1+ x Ti x R y Fe 2−2 x − y O 4, 0.025⩽ y⩽0.15 doped with different rare-earth ions, R=Er, Ce and Nd, were measured in the temperature range 300–750 K. The measurements were carried out as a function of frequency 50–1000 kHz X-r...
