摘要：

A series of single phase Lu1-xCaxFe2O4 (x= 0, 0.05,0.1) samples were successfully prepared by solid state reaction. The dielectric permittivity/loss at various frequencies and the temperature dependence of the magnetization/resistivity were systematically analyzed. By optimizing Ca-doping, giant dielectric tunability was obtained at low bias electric fields, with great advantages for industrial applications in the near future. Furthermore, the activation energies together with the magnetic moments can be tuned, originating from a variable ratio of Fe2+/Fe3+ by Ca2+ doping. The substitution for Lu3+ by Ca2+ ions provides a novel way to manipulate the dielectric and magnetic properties of charge ordered Lu1-xCaxFe2O4 systems. (C) 2018 Elsevier B.V. All rights reserved.
