自由磁極 的英文怎麼說
中文拼音 [zìyóucíjí]
自由磁極
英文
free magnetic pole-
These particles will aggregate into a certain structure when the applied field yields a critical value. the other is fabricated from " half - metallic " oxides, i. e., ferromagnetic oxides which are predicted theoretically to be completely spin - polarized and really found experimentally to have very high spin - polarization. when a magnetic field is applied to half - metallic granular systems, the resistance will drop rapid and dramatically, which is called the extrinsic magnetoresistance effects in half - metallic granular systems
在磁性材料中，亦有由在理論上具有完全的自旋極化率、在實驗中也被證實具有高自旋極化率的一系列半金屬氧化物材料構成的多晶、粉末等顆粒體系，被發現能在外磁場下發生顯著的電阻下降，即半金屬氧化物顆粒體系中的外稟磁電阻效應。Dmss have attracted a great deal of attention because of their potential application to spin - electronic device and quantum computer dull to their combined properties of both magnetic materials and semiconductors
由於這種材料具有半導體和磁性材料的綜合特性，可望廣泛應用於未來的自旋電子器件以及量子計算機中，從而引起了人們極大的興趣。In this paper, we first investigate the impurity effect ( ba2 + ) on the dielectric and phase transition properties in srtio3 within the framework of the transverse - field ising model ( tim ). then a possible coupling mechanism between the magnetism and dielectric properties in eutio3 is discussed and the magnetic influence on the frequency of the soft - phonon mode is investigated via the heisenberg model, soft - mode theory under the mean field approximation, the second quantization theory and the perturbation theory. and we proceed further investigation on eu1 - xbaxtio3 of
我們發現baxeul _ xtio3 （ o 『 x 『 0 . 2 ）的介電常數和由內察的偏置場導致的電極化除了隨雜質濃度產生相應的變化，同時在磁和介電性質的藕合作用影響下在低溫下偏離通常的量子順電體行為，在尼爾溫度附近出現異常，且磁場通過對最近鄰自旋關聯的作用來影響介電常數和電極化。
