巨磁电阻(GMR)效应使这样一个驱动器的直径不到一英寸，检测在便携式电子设备中存储数据的微小的磁场。
The giant magnetoresistance (GMR) effect allows drives like this one, less than an inch in diameter, to detect the tiny magnetic fields that store data in portable electronic devices.
在以往的电子输运过程中，人们仅需要考虑电子作为电荷的载体，但在巨磁电阻效应中，电子不仅是电荷的载体，而且具有自旋。
We only need consider electron as carrier of electric charge in former electron transporting process, but in GMR effect, electron not only is the carrier of electric charge, but also has spin.
由于在信息存储技术中的应用潜力，人们对巨磁电阻效应发生了浓厚的兴趣。
Because of its application potential of GMR in information storage technology, it's very useful for us to develop GMR researches.
