摘要	Multiferroic Pb(Fe1/2Nb1/2)O-3-PbTiO3 (PFNT) system exhibits the co-operative phenomena with the coexistence of electric and magnetic orders. Through the temperature-dependent dielectric measurements, powder XRD and Raman scattering studies, combining the x-ray absorption fine-structure (XAFS) investigation, the dielectric properties and structures of Pb(Fe1/2Nb1/2)(1-x)TixO3 (x = 0.07 and 0.48) crystals were investigated. The frequency-dependent dielectric anomaly was revealed, which is significantly correlated to the local structure differences and the Fe2+/Fe3+ hoping. The presented results will be useful for understanding and exploring the structure/property relationship beyond this material.
