We need to understand a new class of magnetic materials, magnetic semiconductors, because they have a very high potential in a new subject called spintronics. These materials have the potential to perform both the functions of a semiconductor to process data and a magnetic to store the data.The particular class of compounds based ZnO with a small amount of a transition metal added is particularly promising because they are ferromagnetic at room temperature.However there is a major puzzle: sometimes the magnetism is enhanced when more impurities are added and sometimes the magnetism goes away.In this project we shall investigate if a particular mechanism for this is valid. Understanding this aspect of the magnets will be a very important step towards being able to optimise them for use in spintronics devices. This project is to bring an excellent Indian physicist, Professor Taraphder, to Sheffield to work with the leader of the main UK group working on ZnO in order to solve this problem.

我们需要了解一类新的磁性材料，磁性半导体，因为它们在称为SpinTronics的新主题中具有很高的潜力。这些材料具有执行半导体的功能来处理数据的功能，又有磁性的数据来​​存储数据。特定的基于化合物的ZnO具有少量添加的过渡金属添加了少量的ZnO是特别有希望的，因为在室温下它们是铁磁剂在室温下。有时会增加磁性时的磁性，如果有更多的磁含量，则有时会添加磁性，有时会添加这种项目。有时我们有肯定的有效性。了解磁铁的这一方面将是能够优化用于SpinTronics设备的非常重要的一步。该项目是为了将一位优秀的印度物理学家，塔拉弗教授带到谢菲尔德（Sheffield），与在Zno上工作的主要英国小组的领导者合作，以解决这个问题。
