Abstract:
FeTiNbO6 ceramics have been prepared through a solid-state reaction route. The room-temperature dielectric relaxation and magnetic characteristics of FeTiNbO6 were investigated together with the crystal structure. The present ceramics were characterized by tetragonal rutile structure in space group P4(2)/mnm. An obvious dielectric relaxation with strong frequency dispersion and following the modified Debye equation was detected in low temperature range, which can be assumed to the carrier hopping process between Fe2+ and Fe3+. Temperature dependence of the dc conductivity (sigma(dc)) follows well to Mott variable range hopping (VRH) mechanism. The comparison of the dielectric behaviors between the as-sintered samples and the O-2-annealed samples shows that the low-temperature relaxation in FeTiNbO6 is indeed polarnic in nature. Moreover, the slim magnetic hysteresis loop was detected at room temperature, indicating the weak ferromagnetism in FeTiNbO6 ceramics. (C) 2013 Elsevier Ltd. All rights reserved.
