An improved and novel magnetic element (10; 10'; 50; 50'; 80) including a plurality of thin film layers wherein the bit end magneto-static demagnetizing fields cancel the total positive coupling of the structure to obtain dual magnetic states in a zero external field.

一种改进且新颖的磁性元件(10；10'；50；50'；80)，它含有许多薄膜层，其中单元端部静磁退磁场将抵消这种结构的全部正耦合以在零外磁场下获得双磁态。

Additionally disclosed is a method of fabricating a magnetic element (10) by providing a plurality of thin film layers wherein the bit end magneto-static demagnetizing fields of the thin film layers cancel the total positive coupling of the structure to obtain dual magnetic states in a zero external field.

另外还公开了一种通过提供多个薄膜层来构成一种磁性元件(10)的方法，其中单元端部静磁退磁场将抵消这种结构的全部正耦合以在零外磁场下获得双磁态。

The structure and configuration did not devastated while the hematite hollow particles were deoxidizing to iron hollow particles at 500℃ in hydrogen.

壳层厚度太厚、过快和过慢的升温速率都不利于得到空心结构；500℃氢气气氛还原不改变空心粒子的形貌；空心粒子的粒径取决于聚合物模板粒子的大小，壳层厚度取决于包裹层厚度；空心铁粒子的饱和磁化强度高达到95.26 emu/g，具有较好的抗氧化能力，其磁能积可增大到1.46×103 J/m3，有利于以磁损耗为主要吸波机制的铁磁性空心粒子在吸波材料领域的应用。

This they have since detoxified and created a solely magnetic cellular structure through conscious intent.

The CoFe2O4/TiO2 magnetic nano-photocatalysts has fairly good magnetic property. The X-ray diffraction, transmission electron microscopy and ultraviolet-visible technique were used to analyze the phase structure, size and spectrum response scope of the samples. The XRD indicated the anatase TiO2 was formed when TCF modified by plasma. The size of CoFe2O4 particles was about 20 nm. The diameter of CoFe2O4/TiO2 particles is in the range of 30~40 nm. So the shell of TiO2 enwraps closely around the core and the thickness is in the range of 10~20 nm.

运用VSM技术对样品磁性能进行研究，结果表明：等离子体修饰后的复合材料仍具有较高的饱和磁化强度，可在外加磁场作用下实现催化剂在水中的分离与回收；样品的XRD、TEM和UV-Vis分析测试结果表明：等离子体修饰后的复合材料有锐钛矿型TiO2存在；TEM谱图显示磁核CoFe2O4的平均粒径约为20 nm，TCF复合粒子的粒径约为30~40 nm，TiO2包覆层的厚度为10~20 nm。
