固体中的电子既是电荷的载体,又是自旋的载体。现有的信息技术分别利用半导体的电子电荷特性制造微电子器件,进行信息处理和运算;利用铁磁材料的电子自旋来进行信息存储。自旋电子材料提供了同时利用电子的电荷和自旋两种特性的可能。利用自旋电子材料,可能会实现运算与存储同时进行,这将大大提高工作速度和效率。自旋电子材料提供了优良的自旋量子相干特性,是实行量子计算的很有希望的一种模式,也有可能存在某些新的物理效应。此外,还可能存在与纳米电子材料、分子电子材料相结合的重大发展空间。
The electrons in a solid are both a charge carrier and a spin carrier. Existing information technologies make use of the electronic charge characteristics of semiconductors to fabricate microelectronic devices for information processing and computing, respectively. Electronic spins of ferromagnetic materials are used for information storage. Spin-electron materials offer the potential to exploit both the charge and spin properties of electrons. The use of spintronic materials, may achieve the operation and storage at the same time, which will greatly improve the work speed and efficiency. Spintronic materials provide excellent spin-quantum coherence properties and are a promising model for quantum computing, as are some new physical effects. In addition, there may be significant room for development in combination with nanoelectronic materials and molecular electronic materials.
