摘要：

Multiferroic　ceramics　Bi0.9Ho0.1Fe1-xMnxO3　(x=0.05,　0.10,　0.15)　ceramics　were　prepared　by　solid　state　reaction　method.　X-ray　diffraction　(XRD)　indicated　that　Bi0.9Ho0.1Fe1-xMnxO3　ceramics　exit　secondary　phase　Bi2Fe4O9　at　about　27°.　With　increasing　Mn4+content,　the　gradualmerging　of　the　(104)　and　(110)　peaks　and　the　gradual　disappearance　of　the　(006)　peakindicateda　structural　transition　from　the　rhombohedral　to　the　tetragonalwere　observed.　SEM　images　indicated　that　the　grain　size　increases　with　increasing　Mn4+　ions　dopant　concentration.　Ferroelectric　performance　testing　were　shown　that　all　samples　present　the　typical　lossunsaturated　ferroelectric　behavior,　as　the　P-E　loops　were　not　saturated.　The　remanent　polarization　of　Bi0.9Ho0.1Fe1-xMnxO3　(x=0.05,　0.10,　0.15)　ceramics　increased　and　then　decreased　sharply.The　M-H　curves　recorded　at　room　temperature　revealed　that　the　remanent　magnetization　increasedwith　increasing　Mn4+　content.　In　other　words,　the　unique　M-H　loops　indicated　that　the　Bi0.9Ho0.1Fe1-xMnxO3　ceramics　have　a　metamagnetic　transition　with　increasing　magnetic　filed.
