Antiferromagnets recently have shown potential in information technology, as they produce much faster dynamics and are more stable against perturbations compared to recent ferromagnetic devices. However, due to their missing net magnetization, there are limited options to manipulate antiferromagnets. To overcome this problem hybrid systems of ferromagnets and antiferromagnets are studied, which combine the advantages of both materials in spintronics devices.

In my Bachelor thesis I studied the antiferromagnet hematite and investigated its magnetic phases below the Néel temperature in dependence of an eternal magnetic field.

Currently I am investigating the formation of a domain structure in antiferromagnets for different hybrid systems. For this I consider magnetoelastic effects on the interface of the antiferromagnet and the other material and search for the stresses that influence the magnetic structure of the antiferromagnet with both analytical methods and simulations.
