摘要
FePt磁性材料因具有高矫顽力良好的单轴磁晶各向异性极低的超顺磁临界尺寸良好的化学稳定性和热稳定性，在超高密度垂直磁记录介质生物医学等领域应用前景广阔。本文利用脉冲电沉积法制备了FePt共沉积薄膜Fe/Pt多层膜和FePt纳米粒子；用湿化学法制备了FePt纳米粒子，并用SiO_2对其进行表面修饰。利用XRD、FESEM、TEM、EDS、FT-IR、VSM研究了制备条件对产物组成形貌晶体结构磁性能等方面的影响规律。
研究结果表明：脉冲电沉积法制备的FePt共沉积薄膜均含有较多的氧；脉冲电压对薄膜组成影响很大，沉积时间与薄膜厚度成正比。调节脉冲电压和沉积时间可获得不同组成厚度的共沉积薄膜； Fe/Pt比例接近1时，共沉积薄膜的含氧量很高且薄膜组成对电压的变化非常敏感ǎ未热处理的FePt薄膜为面心立方（fcc）结构；氢气中550℃热处理30min后，有少量的fcc结构转变成面心四方（fct）结构，显示一定的硬磁性。
多层膜工艺能有效降低FePt薄膜中的含氧量及由fcc结构向fct结构的相变温度。通过适当调节电沉积参数制备出了组成为Fe_(33)Pt_(37)O_(30)和Fe_(37)Pt_(35)O_(28)的Fe/Pt多层膜。组成为Fe_(33)Pt_(37)O_(30)的多层膜在氢气中600℃热处理30min，氧含量降低了71%，晶体结构由无序的fcc结构转变为有序的fct结构并出现明显（110）织构；多层膜由软磁性转变成硬磁性，矫顽力达到约1420Oe。
湿化学法制备的FePt纳米粒子组成为Fe52Pt48，粒子呈球形，平均直径2nm左右。Fe_(52)Pt_(48)纳米粒子是无序的fcc结构，室温显示超顺磁性；氩气中700℃热处理30min后转变为有序的L1_0-FePt相，有序度约为0.8。PEM制备的球形FePt纳米粒子为富Pt组成，平均直径2.5nm左右，是无序的fcc结构，也显示超顺磁性；氩气中700℃热处理30min，富Pt的FePt纳米粒子转变为以有序的面心立方L1_2-FePt_3相为主并伴有少量L1_0-FePt相的组成，显示一定的硬磁性。
反相微乳液法制备SiO_2包覆FePt（FePt@SiO_2）复合纳米粒子过程中，壳层的生长是SiO_2初级粒子在FePt表面的异相成核聚集生长。调整TEOS加入量可获得2~20nm的壳层。SiO_2包覆可改善复合粒子的分散性，对FePt纳米粒子饱和磁化强度影响不大，未热处理的FePt@SiO_2显示超顺磁性。SiO_2包覆能有效抑制热处理过程中粒子的长大团聚及fcc结构向fct结构的相变。热处理后的FePt@SiO_2复合纳米粒子与未包覆的FePt纳米粒子相比，饱和磁化强度剩余磁化强度略有降低，矫顽力基本不变。
Because of its high coercive force, ultra-high single axis magnetic crystalanisotropy, very low super paramagnetic critical size and good chemical and thermalstability, FePt magnetic materials has great potential application for future ultra-highdensity perpendicular magnetic recording media, biomedical domain and so on. In thisthesis the FePt films, Fe/Pt multilayers and FePt nanoparticles（NPs） were depositedby pulse electroplating method (PEM). The FePt NPs also were synthesized by wetchemical method, and the surfaces were modified by SiO_2. The relationships betweenthe preparation conditions of samples and the composition, morphology, crystalstructure, magnetic performance were investigated by XRD, FESEM, TEM, EDS,FT-IR and VSM.
The results were as follows: All FePt co-deposition films prepared by PEMcontained a lot of oxygen content. Pulse potential had great effects on thecompositions of films. The thickness of thin film was proportional to deposition time.FePt co-deposition films with different compositions and thicknesses could beobtained through changing pulse potential and deposition time. The compositions ofthin films were more sensitive to pulse potential and with higher oxygen containingwhen the ratio of Fe/Pt was closer to1. All FePt co-deposition films as-depositionwere face-centred cubic (fcc) structure. A small amount of fcc structure FePt changedinto face-centred square (fct) structure after the films were heated treatment inhydrogen atmosphere at550℃for30min, and the films became some hard magnetic.
Multilayer technology could effectively reduce the oxygen content of filmsas-deposition and the FePt phase transition temperature from fcc structure to fctstructure. The Fe/Pt multilayers with compositions of both Fe_(33)Pt_(37)O_(30)andFe_(37)Pt_(35)O_(28)were deposited through adjusting electrodeposition parameters. Theoxygen content of Fe/Pt multilayers with compositions of Fe_(37)Pt_(35)O_(28)reduced by71%after600℃treatment in hydrogen for30min, and the crystal structure of FePtchanged from promiscuous fcc structure into ordered fct structure in which the (110)texture appeared; The soft magnetic of the multilayers changed into hard magnetic.The coercive force of the multilayers increased obviously to about1420Oe.
The FePt nanoparticles with the composition of Fe_(52)Pt_(48)were synthetized by wet chemistry method. The as-synthetized FePt NPs were spherical with promiscuous fccstructure. They showed superparamagetism at room temperature and the coerciveforce of them was approximately zero. After heat treatment in argon at700℃for30min, the FePt NPs changed into ordered L10-FePt and the degree of order was0.8around. Spherical FePt NPs were prepared by PEM. They are rich-Pt and the averagediameter was about2.5nm. The as-prepared NPs were also superparamagetism atroom temperature with promiscuous fcc structure. After heat treatment in argon at700℃for30min, the rich-Pt NPs changed into ordered fcc structure L1_(2-)FePt_3phasewith a small quantity of L10-FePt phase and showed some hard magnetic.
In the process of FePt@SiO_2composite NPs prepared by reverse microemulsionmethod，the primary particles of SiO_2were heterogeneous nucleated, aggregated andgrown on the surface of FePt NPs. The thickness of SiO_2shell layers could range from2nm to20nm through adjusting the addition amount of tetraethoxysilane. Thedispersion of composite NPs could be improved by SiO_2modification. Theas-synthetized FePt@SiO_2composite NPs showed a good superparamagnetic withlittle change in the saturation magnetization. The growth and aggregation ofFePt@SiO_2composite NPs and the phase transition of FePt from fcc structure to fctstructure in the heat treatment process were effectively restrained by SiO_2modification. After heat treatment, compared with FePt, the saturation magnetizationand remanent magnetization of FePt@SiO_2composite NPs reduced slightly but thecoercive force kept unchanged.
