The tem shows lots of nano silica particles circumfuse on the surface of the micro fe particles after the micro fe coated by silica. the sem analysis shows the same result. the vsm shows the micro fe particles have almost no remnant magnetism and coesive. the saturation magnetization decrease with the feed content of teos remenant magnetization and coesive are little
隨著teos的投料的增加,材料飽和磁化強度呈下降趨勢,微米粒子磁化曲線通過原點,表面包裹后,剩磁與矯頑力變化很小對于微米鐵粉,其磁疇變化較快,沒有剩磁與矯頑力。Vibrating samples magnetometer ( vsm ) testing implied that yig were of ferrimagnetism, and cerium substitution had effects on saturation magnetization ( ms ), residual magnetization ( mr ) and coercive force ( hc )
Vsm測試結果表明yig屬于亞鐵磁性物質, ce離子的摻雜對飽和磁化強度( ms ) 、剩餘磁化強度( mr ) 、矯頑力( hc )都有一定的影響。The finer the grain is, the higher the magnetic properties are, such as the improvement of coercivity. according to the theory of remanence, the intensity of remanence is in direct proportion to the density of magnet and ms. the improvement of remanence resulted from the interaction of density of magnet and ms, but the ms took the more important role
究其原因:晶粒的細化可以提高磁體的矯頑力;而根據剩磁的理論公式,剩磁與磁體密度和飽和磁化強度成正比,剩磁的提高是磁體密度和飽和磁化強度的提高的綜合效果,但其中飽和磁化強度的提高佔主導地位。With the increasing of the doping amount of these four rare earths, both the specific saturation magnetization and the specific remanent magnetization decrease gradually to the same extent
隨著稀土摻雜量的增加,樣品的比飽和磁化強度和比剩餘磁化強度均隨之下降,且摻雜各種不同稀土元素的下降幅度大體相同。The effects of the different kinds of rare earths and the doping amount of them on magnetic properties of bafe, 2o19 ultrafine powders ( including the specific saturation magnetization, the specific remanent magnetization and coercive force ) were firstly discussed systematically
首次查明了鋇鐵氧體粉末的磁性能(包括比飽和磁化強度、比剩餘磁化強度和內稟矯頑力)隨稀土元素種類及其摻雜量的變化規律。The particle size of the product is about 16 nm with perfect crystal structure. the product exhibits superparamagnetism and strong magnetic responsivity, the saturation magnetization being 55. 4emu / g and the magnetic susceptibility being 8. 28 10 - 3emu / oe. the particle size distribution is homogeneous with good dispersion. 2
產物具有完美的晶體結構,粒徑約16nm ,比飽和磁化強度為55 . 4emu g ,磁化率為8 . 28 10 ~ ( - 3 ) emu oe ,磁響應性強,具有超順磁性,剩磁和矯頑力均為零,粒徑分佈均勻,分散性良好。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。The comparison between the magnetic properties of ndfeb magnet by microwave magnetic field sintering and those of magnet by conventional sintering technology shows that the brwas improved 50 %, the hcb was improved 8 %, and the ms was improved 40 %
