磁疇磁化強度 的英文怎麼說
中文拼音 [cíchóucíhuàqiángdù]
磁疇磁化強度
英文
domain magnetization-
The tem shows lots of nano silica particles circumfuse on the surface of the micro fe particles after the micro fe coated by silica. the sem analysis shows the same result. the vsm shows the micro fe particles have almost no remnant magnetism and coesive. the saturation magnetization decrease with the feed content of teos remenant magnetization and coesive are little
隨著teos的投料的增加,材料飽和磁化強度呈下降趨勢,微米粒子磁化曲線通過原點,表面包裹后,剩磁與矯頑力變化很小對于微米鐵粉,其磁疇變化較快,沒有剩磁與矯頑力。It is found that the specific saturation magnetization decreases with the decrease of the nanocrystallites grain size. the dominating reason is the grain size of the nanocrystallites less than the critical size of the single magnetic domain
發現對于純凈的納米晶粒來說,飽和磁化強度隨著晶粒線度的減小而減小,這主要是因為所制備的納米晶微粒的晶粒線度小於單疇顆粒的臨界粒徑。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。1. based on magnetic domain energy theory, magnetomechanical effect of single cycle load is studied and it is analysed emulationally that magnetic memory characteristic parameters of single cycle load. magnitude and direction of accessional magnetic intensity are made sure of the ferromagnetism material derived from single cycle load
全文主要研究內容如下: 1 .基於磁疇結構的能量理論,對單周期載荷力磁效應進行了研究,並對單周期載荷磁記憶特徵量進行了數值模擬,確定了鐵磁性材料單周期載荷的應力附加磁化強度的大小和方向。分享友人
