In the quest for a nanostructure capable to support nonlinear excitations we have studied the behavior of a possible magnetic nanoparticle with the same geometry as the organic molecule Kekulene. Exchange and dipole interactions are considered between the constituting particles in the molecule. Using Monte Carlo simulations, we have found that stable magnetic vortices develop and are stable in a wide range of temperature ($T$) and dipole anisotropies ($\delta =D/J$). The importance on synthesizing such molecule grounds in the possibility of building real planar structures. It is worthy to mention that such Kekulene-like molecule is a planar structure with atomic thickness, which is a great advantage compared with other possibilities being of size at least 10 times smaller than earlier proposed permalloy nanodots.

为了寻求能够支持非线性激发的纳米结构，我们研究了可能具有与有机分子Kekulene相同的几何形状的磁性纳米粒子的行为。考虑分子中构成颗粒之间的交换和偶极相互作用。使用蒙特卡洛模拟，我们发现在很宽的温度范围内都会形成稳定的磁涡流并保持稳定（$Ť$）和偶极各向异性（$\delta =d/Ĵ$）。在构建真实的平面结构的可能性中，合成此类分子基的重要性。值得一提的是，这种类似Kekulene的分子是具有原子厚度的平面结构，与尺寸比先前提出的坡莫合金纳米点小至少10倍的其他可能性相比，这是一个很大的优势。
