A brief overview of magnetoresistance effect this chaper aims at a brief overview of the history , progress and current status of all kinds of magnetoresistance materials , such as omr , amr , gmr and cmr and so on . by these illustration , we may acquire a basic sight on magnetoresistance effect as well as magnetoelectronics 包括正常磁電阻效應( omr ) 、各向異性磁電阻效應( amr ) 、巨磁電阻效應( gmr ) 、特大磁電阻效應( cmr ) ,通過本章的介紹,我們將對磁電阻效應以及磁電子學都有一個概括的了解。

Otherwise , using the ta buffer layer can effectively reduce the surface roughness . in addition , measured by our measurement system , the polycrystalline the film has similar negative magnetoresistance effect to single - crystalline film , so it is potential to be applied in spintronic devices 通過磁電子輸運測試系統研究制備的薄膜還發現多晶fe _ 3o _ 4具有同單晶fe _ 3o _ 4類似的負磁電阻特性,因此有望將多晶fe _ 3o _ 4薄膜應用到自旋電子器件中。

Mere giant magnetoresistance , which debuted in commercial hard drives back in 1998 , represented the first example of so - called spintronics , or electronics based not on charge but spin , the property of an electron that makes it act like a tiny bar magnet 不過僅有在1998年的商業化硬盤上首度亮相的巨磁電阻效應才是稱之為自旋電子- -或非基于電荷而是旋轉(電子的這個特性使它像一個小型的條形磁鐵)的電子- - - -的首個例子。

The mram needs to be of a large magnetoresistance ( mr ) effect at room temperature and lower magnetic field , in order to demands of practical application . however , the large tunneling mr effect is strongly dependent upon electrode material , which is of high spin polarization 采用高自旋極化率( p )的材料是產生大的隧穿磁電阻( tmr )效應的關鍵之一,而半金屬( half - metal )鐵磁材料的自旋極化率p理論上可達100 。

And sort of like a b - movie franchise , researchers keep uncovering new , more powerful forms of magnetoresistance : colossal magnetoresistance , ballistic magnetoresistance and ( my personal favorite ) extraordinary magnetoresistance , to name three 有些像是拍攝粗制濫造的電影,研究員們不斷地發現了新的更為強大的磁電阻形式:特大磁電阻效應,彈道磁電阻效應,還有(本人最喜歡的) ”非凡“磁電阻效應,僅列出三個為例。

Comparing to the influence of the bias , the variation of the giant - magnetoresistance induced by change of temperature is smaller . it becomes important only in the situation when the variation of temperature is large 與偏壓的影響相比,溫度的改變所引起的巨磁電阻的變化相對較小,只有在溫度變化較大時才有顯著的影響。

In the case when the temperature becomes near to 0 ? k , the decrease of temperature makes the giant - magnetoresistance smaller when the bias is positive , it makes the giant - magnetoresistance larger when the bias is negative 在絕對溫度零度附近, u為正時,溫度下降導致巨磁電阻減小; u為負時,溫度下降導致巨磁電阻增加。

The percentage increase in resistance , called the magnetoresistance ( mr ) , was so big and so unusual that my team immediately redirected its efforts to explain the fundamental physics of this new effect 磁阻(電阻增加的百分比)的值相當大而且不尋常,使我的小組立刻改變研究方向,轉而想要解釋這個新效應的基礎物理。

On one hand , in grain regions of films , the strong inter - duster interaction , mentioned as mean field , leads to the colossal magnetoresistance effect ( cmr ) 與此同時,薄膜的拓撲形態分為顆粒區域和顆粒邊界區域。在顆粒區域內,小聚集體之間具有強關聯耦合作用,是這種非均勻體系龐磁阻效應的成因。
