Ternary　system　ceramic　0.2Pb(Zn1/3Nb2/3)O-3-0.8Pb(Zr-0.5,Ti-0.5)O-3(1-x)(Ni51.5Mn25Ga23.5)x　prepared　by　solid　state　reaction　were　investigated.　The　test　methods　such　as　XRD　test　and　VSM　test　were　applied　to　analyze　its　properties　and　structure.　X-ray　diffraction　(XRD)　indicates　that　Ni51.5Mn25Ga23.5　has　all　soluted　into　0.2Pb(Zn1/3Nb2/3)O-3-0.8Pb(Zr-0.5,Ti-0.5)O-3　lattice　first　and　then　Ni51.5Mn25Ga23.5　exists　in　composite　system　by　separate　phase.　Thus　it　makes　the　diffraction　peaks　shift　to　right.　Ferroelectric　tests　show　that　remanent　polarization　is　decreased　with　x　increasing　and　coercive　field　is　first　decreased　and　then　increased.　The　magnetic　field　dependence　of　magnetization　indicates　remanent　magnetization　increasing　with　x　increasing.
