巨磁阻效应的英文
giant magnetoresistance
例句与用法
- On the other hand , tiny clusters in the grain boundary regions are of no interactions , hence result in a temperature behavior similar to the above one of magnetic granular alloys
在颗粒边界区域内，小聚集体之间没有耦合作用，导致低温区域出现类似颗粒复合膜中巨磁阻效应的温度行为。 - Within the framework of the latter one , the gmr dependence on temperature and volume - fraction is discussed in the paper , with consideration of different kinds of magnetic entities
本文采取了后一条途径，具体考虑多种磁组分形态对巨磁阻效应的影响，详细讨论了巨磁阻的温度效应和浓度效应。 - There are mainly two ways of theoretic study on gmr in magnetic granular alloys . one is to extended the quantum or quasi - classical treatments of gmr in multilayers to the one in magnetic granular systems . the other is a phenomenological method which adopes effective medium approxiation ( ema ) and two - channel model directly
颗粒复合膜中巨磁阻效应理论研究主要有两条途径：一条是将多层膜中巨磁阻效应的量子方法和半经典方法推广到颗粒复合体系，另一条是直接利用有效介质理论和双通道模型的唯象方法。 - The discovery of giant magnetoresistance effect has attracted much attention to research of magnetic transport in inhomogeneous systems , which depends on spin of electrons . the magnetoresistance in such two inhomogeneous systems as magnetic granular alloys and doped pervoskite manganite fflms is usually considered due to spindependent scattering
巨磁阻效应的发现，导致了一个如何正确看待非均匀系统中磁输运性质的问题，并使电子输运状况依赖于自旋内禀属性的物理观念逐渐形成。
百科释义
巨磁阻效应（Giant Magnetoresistance）是一种量子力学和凝聚态物理学现象，磁阻效应的一种，可以在磁性材料和非磁性材料相间的薄膜层（几个纳米厚）结构中观察到。这种结构物质的电阻值与铁磁性材料薄膜层的磁化方向有关，两层磁性材料磁化方向相反情况下的电阻值，明显大于磁化方向相同时的电阻值，电阻在很弱的外加磁场下具有很大的变化量。巨磁阻效应被成功地运用在硬盘生产上，具有重要的商业应用价值。
