[UNESP]2014-05-272014-05-272010-12-01Proceedings of the 2010 IEEE International Symposium on the Applications of Ferroelectrics, ISAF 2010, Co-located with the 10th European Conference on the Applications of Polar Dielectrics, ECAPD 2010.http://hdl.handle.net/11449/72053The dielectric properties of the 0.65[Pb(Mg 1/3Nb 2/3)O 3]-0.35PbTiO 3 ferroelectric ceramic composition were investigated viewing the capability to be used for tunable microwave applications. The dielectric response has been studied for three selected temperatures (300 K, 370 K and 400 K), below the paraelectric- ferroelectric phase transition temperature, as a function of the applied 'bias' electric field. The obtained dielectric tunability was found to be around 60 %, under an electric field of 19 kV/cm, which makes the studied ceramic composition an excellent candidate for application in the electro-electronic industry, as tunable devices. © 2010 IEEE.engCeramicsDielectric properties)FerroelectricsCeramic compositionsDielectric responseDielectric tunabilityElectronic industriesFerroelectric phase transition temperaturesParaelectricsTunable deviceTunable microwave applicationsCeramic materialsElectric fieldsFerroelectricityLeadFerroelectric materialsTrabalho apresentado em evento10.1109/ISAF.2010.5712274Acesso aberto2-s2.0-799530515946725982228402054
