The pinning effect

反磁化核在外磁场作用下长大成为反磁化畴,然后通过畴壁位移实现反磁化。产生反磁化核的地方一般是晶体缺陷、掺杂物等,缺陷数目、掺杂物等越多,反磁化核越容易形成,矫顽力也就越低。 … Visa mer 面缺陷模型是指在一个晶面两侧的原子受到破坏所形成的层错、晶粒间界、两相边界、晶体表面等。面缺陷对畴壁的钉扎作用主要是通过它们磁性参数与基体之间的差异和变化实现的 Visa mer 点缺陷是指晶格点阵上的杂质原子、空穴、间隙原子、原子位错等。点缺陷对畴壁的钉扎作用主要从点缺陷所造成的应力场和磁性常数的变化来体现。由于畴壁面积较大,与之相互作用的点缺陷数 … Visa mer 钉扎点,是指位错移动的障碍物自身的几何尺度远远小于相邻障碍物之间的距离,因此可以将障碍物视为钉扎点的情况。在金属材料的强化方式中,阻碍位错滑移的单个固溶原子和通常的第二相粒子,以及对于水平方向上移动的位错来说竖 … Visa mer Webb13 aug. 2014 · This study explores the working mechanism and the influence factor of the pinning effect of advancing sessile droplets on micropillared superhydrophobic surfaces.
