The main goal of the project is to gain essential knowledge on the relation between morphology and magnetic properties by generating defined metal chalcogenide nanocrystals with ferromagnetic (EuO, EuS), ferrimagnetic (Fe3O4) or antiferromagnetic (Fe2O3) properties and unusual or new shapes, followed by a magnetic characterization including state-of-the-art computer simulations. The second focus is on exploring 2D and 3D arrays of those particles towards the emergence of cooperative magnetic phenomena, such as complex, highly frustrated magnetic states that can be exploited in magnonic or spintronic devices.

该项目的主要目标是通过生成具有铁磁（EuO，EuS），亚铁磁（Fe3O4）或反铁磁（Fe2O3）特性和不寻常或新形状的定义金属硫属化物纳米晶体，获得有关形态和磁性之间关系的基本知识，然后进行磁性表征，包括最先进的计算机模拟。第二个重点是探索这些粒子的2D和3D阵列，以出现合作的磁现象，例如可以在磁振子或自旋电子器件中利用的复杂的、高度受抑的磁态。
