magnetoresistance

基本解释

Today, spins are often made using a filter that exploits the phenomenon of giant magnetoresistance (GMR).
目前，科學家一般利用根據巨磁阻傚應建造的過濾器來極化電子束流。
One well-established way in which data are stored employs magnetoresistance, a property discovered in 1856 by William Thomson, later Lord Kelvin.
通過磁阻對數據進行存儲是一個切實可行的辦法, 磁阻是由威廉·湯姆遜(後稱開爾文男爵)在1856年發現的一個磁場傚應.
Since a magnetic field changes the resistance of ordinary metals by only a fraction of a percent, they dubbed this phenomenon "giant magnetoresistance," or GMR.
由於磁場變化對普通金屬衹會造成遠遠不到百份之一的電阻變化，這種現象被稱爲“巨磁電阻”或巨磁阻GMR。

They won the 2007 Nobel prize in physics for uncovering this so-called giant magnetoresistance effect.
FORBES: Spin Is In
Over the past 30 years several new forms of magnetoresistance have been found.
ECONOMIST: Spintronics
Physicists thought that ballistic anisotropic magnetoresistance would show itself when a magnetised metal wire a few atoms across was placed in a second magnetic field.
