查询词典 magnetic field

Modeling and Simulation of the magnetic field regenerated by the permalloy microelements was performed.

概述了磁珠微流控分离系统及在生物医学工程中的应用，总结了磁珠微系统化方面的研究进展，提出了自己的研究方案； 2。

The anisotropic magnetoresistance and saturation magnetic field of the Permalloy thin films (Ni0.81Fe0.19) sputtered on a nonmagnetic (Ni0.81Fe0.19)0.66Cr0.34 buffer layer were measured. The AMR variations of the films after annealing and the size effect of the AMR stripes after etching were emphatically studied, and a qualitative analysis was proposed through a statistic model. The simulation results agree with the experiments.

研究了以非磁性（Ni0.81Fe0.19）0.66CR0.34薄膜作为过诞层的坡莫合金Ni0.81Fe0.19薄膜的磁电阻效应和饱和磁场，分析退火处理对样品饱和磁场的影响和经刻蚀后的磁电阻效应膜线的尺寸效应，并建立一个统计模型定性分析了其性能变化的机理，计算结果符合实验。

Similarly, the AMR begin to increase and then decrease with increasing the thickness d of the seed layer, and has a maximum value at a critical thickness d of 5.32nm. Compared to the permalloy films deposited on Ta seed layer ,the AMR enhancement of 10%-46% is observed in the permallay films deposited on (Ni0.82Fe0.18)1-xNbx seed layer.(2) The coercivity Hc1 obtained for magnetic field H applied paralley to the easyaxis is large than Hc2 for H applied perpendicular to the in-plane easy axis, and both of coercivity are consistent with the change of x.

2沿样品易轴方向的矫顽力Hc_1比难轴方向的矫顽力Hc_2大，两者随Nb原子的百分含量x的变化是一致的，饱和磁化强度Ms随x的增大先增大后减小，在x=27.1％处，Hc_1和Hc_2都比较小，而Ms则达到最大；种子层厚度d不能明显改变坡莫合金薄膜的磁性能；与以传统材料Ta为种子层的坡莫合金薄膜相比，以Ni_(0.82Fe_(0.18)_(0.829)Nb_(0.271)为种子层的坡莫合金薄膜的矫顽力只有轻微减小，但是Msg 以w讪Fq.t）lkNk为种于层的坡莫合全薄膜的各向异性戳电阻及磁性能研究却要大，mk坡莫合金层厂度！

A measure of the effect of the medium on the magnetic field B when subject to a magnetizing force H: B = 0 in SI system, B = H + 4πI in cgs system, where 0 is the permeability of free space.

是介质在磁场 B 中所受磁化力为 H 时产生的效应：在国际单位制中 B = 0 在厘米-克-秒制中 B = H + 4πI 其中 0 为自由空间磁导率。
