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.
