论文摘要
我们已经研究了磁性隧道纳米结对磁倍率大小的横向尺寸的影响。在建模过程中，右接触的大小是固定的，而左侧的大小逐渐变化，直到它们重合为止。我们发现在不匹配的横截面的纳米接触中，隧道磁磁磁力（TMR）急剧下降。这可以通过电子密度的空间分布的特殊性来解释，这对于多数族裔和少数族裔状态是不同的。在基于TMR的Nanodevices的设计中必须考虑发现的效果。
We have studied the influence of the transverse size of a magnetic tunnel nanojunction on the magnitude of the magnetoresistance. During modeling, the size of the right contact was fixed, while the size of the left one gradually changed until they coincided. We found a sharp drop in the tunneling magnetoresistance (TMR) in nanocontacts with mismatched cross section. This can be explained by the peculiarities of the spatial distribution of the electron density, which is different for majority and minority-spin states. The discovered effect must be taken into account in the design of TMR-based nanodevices.
