antiferromagnetic 中文意思是什麼

antiferromagnetic 解釋
反鐵磁的
  1. An anomalies in the dielectric constants and loss tangent have been observed experimentally in the ferroelectromagnet near the antiferromagnetic transition temperature, indicative of a coupling between the ferroelectric and magnetic ordering, but the nature of the mechanism of magnetoelectric coupling and the form of interaction is still an important and debated issue

    而另一類是鐵電磁體，它除了具有一般磁電體的性質外，還由於固有的本徵磁有序和鐵電有序的耦合使之存在自發的磁電效應。實驗上已經發現了由於自發的磁電耦合導致的介電異常和損失正切。
  2. The magnetic ground state of lafe _ ( 11. 4 ) al _ ( 1. 6 ) cx compound changes from antiferromagnetic to ferromagnetic for x > 0. 06 and the curie temperature increased monotonously with the increase of carbon content. a large magnetic entropy change was obtained near the phase transition temperature and the refrigerant capacity is good

    當碳含量高於0 . 06時，化合物的基態由反鐵磁變為鐵磁且居里溫度隨c含量的增加向高溫區移動，在各自相變溫度附近保持較大磁熵變，具有良好的磁製冷能力。
  3. The spin operator ' s commutation relations in one dimensional quantum antiferromagnetic chains and lagrangina expression

    一維量子反鐵磁鏈格點自旋對易關系與廣義拉氏表示
  4. By means of the measure of entanglement called " concurrence ", we study the entanglement in heisenberg a single molecular magnets dimer v + with a strong magnetic field and find that thermal entanglement exits for both ferromagnetic ( fm ) and antiferromagnetic ( afm ) cases. in fm case entanglement vanishes for anisotropic parameter value = 0, while in afm case, entanglement exits in the whole region of anisotropic parameter 0 < < 1. an interesting conclusion is that the critical temperature is independent of the magnetic field

    應用糾纏的一種測量「 concurrence 」 ，對自旋二聚物v ~ （ 4 + ）在外加強磁場情況下的熱糾纏進行了研究，發現對于鐵磁和反鐵磁兩種情況，熱糾纏都存在；鐵磁情況下，在各向異性常數等於零的時候糾纏消失，而對于反鐵磁在整個各向異性常數變化范圍內糾纏都存在，有意思的是我們發現臨界溫度獨立於磁場b ，我們也研究了糾纏度隨各向異性常數、磁場和溫度的變化。
  5. By using the new method, the eigenstate of xxz antiferromagnetic model is solved, which is revealed to be 5 ? l, l ) coherent state. in the third chapter, we discussed the relation between the bogoliubov - valatin transformation and the algebraic method based upon the bcs model hamiltonian at first. then, we diagonalized the ssh model hamiltonian for the first time by using the algebraic diagonalization method

    第三章我們首先使用bogoliubov - valatin變換對角化和新的代數對角化兩種方法，將bcs模型的哈密頓量對角化，並對兩種對角化方法作了比較、討論；其後，本文首次給出了代數對角化方法在ssh模型中的應用，並且其結果也與bv變換法的作了同上面bcs模型類似的討論。
  6. Zero - temperature magnetic properties of ferromagnetic double layers with interlayer antiferromagnetic coupling

    復合層合管強度的理論計算
  7. In the first chapter of the article we introduce the bogoliubov - valatin transformation theory based upon the xxx antiferromagnetic model. in the second chapter, a new algebraic diagonalization method is presented

    第二章介紹一種新的代數對角化方法的理論，這種方法可以將具有半單李代數結構的哈密頓量對角化。
  8. For all doping concentrations, the coupling between cr and the nearest neighbor n is found to be antiferromagnetic, and the cr 3d states hybridize strongly with n 2p states, which are in agreement with the band calculations

    對于不同的摻雜濃度， cr原子與最近鄰n原子之間均為反鐵磁偶合， cr原子的3d電子與n原子的2p電子之間有很強的雜化，這和晶體的能帶計算方法得到的結果一致。
