论文摘要
自十年世纪以来，塔尔伯特效应就在光学方面已知，并发现了各种技术应用。在本文中，我们在微磁模拟的帮助下演示了这种自我成像现象，用于在薄薄的铁磁膜中传播的自旋波，磁性磁化不足。我们表明，通过波浪现象的一般分析所产生的近似分析公式可以在很大程度上描述获得的自旋波的Talbot地毯的主要特征。我们的结果表明，在低频和高频下对塔尔伯特效应的可行实验实现的途径，并提供了有趣的效果和镁化的应用。
The Talbot effect has been known in optics since XIX century and found various technological applications. In this paper, we demonstrate with the help of micromagnetic simulations this self-imaging phenomenon for spin waves propagating in a thin ferromagnetic film magnetized out-of-plane. We show that the main features of the obtained Talbot carpets for spin waves can be described, to a large extent, by the approximate analytical formulas yielded by the general analysis of the wave phenomena. Our results indicate a route to a feasible experimental realisation of the Talbot effect at low and high frequencies and offer interesting effects and possible applications in magnonics.
