The　influences　of　annealing　temperature　on　the　phase　transition,　dielectrical,　and　ferroelectric　response　of　0.65Pb(Mg1/3Nb2/3)O-3-0.35PbTiO(3)　(PMN-35PT)　have　been　investigated　in　detail.　X-ray　diffraction　combined　with　Raman　spectra　analysis　indicated　that　the　samples　annealed　below　1100　degrees　C　show　a　complete　perovskite　structure　while　at　higher　temperature,　the　volatilization　of　PbO　results　in　the　formation　of　the　pyrochlore　phase.　The　relative　intensity　I-740/I-800　of　A(1g)　mode　increased　with　the　increase　of　annealing　temperature,　indicating　the　phase　transition　to　the　tetragonal　side.　The　annealing　can　eliminate　the　grain-boundary　layer,　release　the　internal　stress,　and　improve　the　homogeneous　distribution　of　polar　nanoregions,　resulting　in　the　increase　of　dielectric　constants　and　the　decrease　of　relaxor　behavior.　Moreover,　the　squareness　R-sq　from　the　P-E　hysteresis　loop　displayed　the　enhanced　trend　with　the　increase　of　annealing　temperature,　which　can　be　attributed　to　the　descending　of　B-site　cation　order.
