磁性材料从古至今已经有很悠久的历史了，而它也一直被人们所用到，可以说是当今世界不可缺少的材料之一了，随着研究的不断进步和发展，人们对磁性材料也越来越了解，磁性材料的特殊性质也一直在被开发利用。如今的磁性材料在巨磁电阻，磁性液体，磁制冷，软磁，永磁等各领域具有广阔的发展前景。
磁性材料分为有机磁性材料和无机磁性材料，两者在不同的领域都有着广阔的前景，本课题研究主要是无机磁性材料。常用的无机磁性材料包括铁，钴，镍，锰及其合金，氧化物和稀土金属永磁材料等。
而在20世纪90年代以来，随着纳米技术的发展，磁性材料已步入磁性纳米材料的新纪元，其各方面性质都发生了巨大的变化，具有非常广阔的前景，如今已渐渐成为科研的热点。
本课题主要研究的是制备出Au修饰的Fe3O4@Ag复合纳米颗粒，并对其磁热效应、吸收光谱和SERS活性进行测量。

Answer 1

The magnetisable material has very long history from ancient times to the present, and it has used by people all the time, can be said to be one of the indispensable materials in our times, and develop with the constant progress of studying, people understand the magnetisable material more and more too, the special properties of the magnetisable material have been developed and utilized too. The magnetisable material of today is in the huge magnetic resistance, the magnetic liquid, the magnetism refrigerates, soft magnetism, every field such as the permanent magnetism have broad development prospect.

magnetic materials are divided into organic and inorganic magnetic materials, magnetic materials both in different areas, there are broad prospects, the research topics are mainly inorganic magnetic materials. Commonly Used inorganic magnetic materials including iron, manganese, cobalt, nickel and its Alloys, oxides and rare-earth metal magnets, and so on.
Since the 1990s in the 20th century, along with nanotechnology development, magnetic materials has been developed into a new era of magnetic nanomaterials and nanotechnology, and all aspects of their nature, which has undergone tremendous change, with a very broad prospect of scientific research is now becoming the hot spots. .

Preparation of the main research topics are the Fe3O4@Ag of composite nano-particles modified by Au, and its measurement of magnetocaloric effect, absorption and SERS activity.
