The synthesis and properties of potassium sodium niobate based layered magnetoelectric composite material
摘要
Abstract
In this work ,the laminated composites of (K0 .5 Na0 .5 )0 .97 Li0 .03 (Nb0 .8 Ta0 .2 ) O3 (LKNNT)/Co0 .6Zn0 .4 Fe1 .7 Mn0 .3 O4 (CZFM ) were successfully synthesized via the conven-tional solid-state sintering route to afford laminated composite KNNLT/CZFM .Detailed in-vestigations were conducted on optimization of the magnitude of electrical ,magnetic proper-ties and magnetoelectric effect by varying CZFM mass ratios .T he results show that a little ion diffusion between the two phases but no impurity phase occurres in the composites .It was found that the laminated composites possess the largest saturation polarization (Ps ) of 40 .7 μC/cm2 and the largest piezoelectric coefficient (d33 ) of 218 pC/N .The largest ME co-efficient of the laminated LKNNT/CZFM composites reaches up to 256 mV/cm Oe at a bias magnetic field of 300 Oe with the frequency of 1 kHz .关键词
