自發磁化強度 的英文怎麼說
中文拼音 [zìfācíhuàqiángdù]
自發磁化強度
英文
spontaneous magnetization-
The influence on the magnetism and the electron spin resonance ( esr ) over a wide range of composition and temperature have been studied systematically. an obvious symmetric esr signal with a lorentzian lineshape in the paramagnetic regime is observed
本論文邊過選擇磁性離子替代，著眼點在於討論衫雜離子的磁性效應，實驗發現摻雜使樣品的磁結構發生變化，且在低溫時出現磁化強度峰，用摻雜離子自旋旋轉對此進行了解釋。For example, when magnetic material being pressed, magnetic domain, direction and strength of spontaneous magnetization will vary. this phenomenon is called effect of pressing magnet. whichever rearrangement of magnetic domain or direction change of spontaneous magnetization will induces extra shape change of material
如對鐵磁材料施加應力時，往往會導致磁疇、自發磁化方向和強度發生變化，這一現象稱之為壓磁效應，由於得益於壓磁效應的作用，不論是磁疇重新排列還是自發磁化方向發生變化都會引起材料額外的形變，因此在一定應力的作用下鐵磁材料能產生非彈性變形。When the stress at the tip of crack is inflicted on the m - type ferrite particle dispersed in matrix as a second particle, not only the toughness of composites will be pro ved because of the non - elastic area produced by the particle but also the strength change of magnetic field and the stress distribution in the structural ceramics will be detected by the strength of spontaneous magnetization varying while magnetic materials being pressed or drawn
這是因為當結構陶瓷中裂紋尖端的應力作用在彌散於基體內的鐵磁體二相粒子上時，鐵磁粒子不僅在裂紋尖端周圍產生的非彈性區域使復合材料的韌性提高；而且還能利用鐵磁材料在外應力作用下自發磁化強度發生變化的性質，通過測量復合材料在應力作用下磁場強度的變化，探測出結構陶瓷中的應力分佈情況。And then, we specially study the effect of spin interaction ' s anisotropy on the critical temperature tc. from what we have observed we suggest that the critical temperatur tc grows as the anisotropy intensifies, while the system magnetization becomes weaker. the system becomes id if the anisotropy ratio r goes to infinity, and its equilibrium state keeps zero magnetization at any finite temperature, which confirm that there is no observable transition for id system
其後，著重研究了自旋相互作用的各向異性程度r對其臨界溫度t _ c的影響，總結出：隨著系統各向異性程度的增強，系統的臨界溫度向高溫轉移，而系統的磁化強度在不斷的減弱；當r趨近於無窮大時，系統演變為一維系統，系統在任何有限溫度下達到的平衡態始終保持磁化強度為零，這也證實了一維系統不發生相變The evolution of the local spin in a molecular magnet peg and [ mn4 ] 2 interacting with an injected electron is studied, we find that the variation in the magnetization of fe8, [ mn4 ] 2 and the electron spin crucially depends on the strength of the exchange interaction. we calculate the time evolution of the entanglement between the injected electron and fe8, [ mn4 ] 2
在磁性分子fe _ 8和[ mn4 ] _ 2的自旋動力學和糾纏演化的研究中，我們發現糾纏度隨著時間而改變；自旋和糾纏度的振動幅度強烈依靠于交換作用，結果提供了用分子磁體和極化電子進行編碼和讀出數據的可能性。So magnetic material will produce non - elastic shape change when it is pressed or drawn. additionally the strength changes of spontaneous magnetization benefits to detect distribution of stress
另外，作用在鐵磁材料上的應力能使其自發磁化強度發生變化，為檢測材料中的應力分佈提供了依據。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。分享友人
