Cobalt ferrite tape
鈷鐵氧體磁帶 -
According to the sample prepared by hydrothermal method, the doping cations can enter the spinel lattice. rare earth cations mostly occupy position b because of their big radius. cerium are oxidized to ce4 +, whose radius is relatively small, and ce4 + mostly occupies position a. as a whole, the coercivity of cobalt ferrite doped with rare earth element is bigger than that of pure cobalt ferrite
結果表明，對水熱法制備的鐵氧體粒子，雜質離子能夠進入其尖晶石晶格中，並因稀土離子的半徑較大，而絕大部分佔據尖晶石的b位，鈰元素因被氧化成為四價離子，離子半徑相對較小，而主要佔據a位。 -

Zny, ni ( 1 - y ) fe2o4 and cobalt substituted ni - zn soft ferrite powders of zn0. 4ni ( 0. 6 - a ) coa fe2o4 are synthesized by shs. the shs powders and cycle samples are annealing in 1100 for 2h. their magnetic, and micro structural properties are studied using xrd, vsm and sem techniques. the studies reveal that the value of hc mr and ms of the powder of zn yni ( 1 - y ) fe2o4 are maximal when the value of y is 0. 4
研究發現：隨著zno含量（ y值）的增加，粉末產物的矯頑力（ hc ） 、飽和磁矩（ ms ）以及剩餘磁矩（ mr ）先增大（在y = 0 . 4時取得最大值）然後再下降；磁環表面顆粒逐漸長大，孔隙率減少，密度增加；磁環的bs與br先增大再減小，在y = 0 . 4時達到最大；磁環的矯頑力hc是遞減的。
