Neutron Reflectometry on Magnetic Layers (E04 (A05))

• Subject Area: Experimental Condensed Matter Physics
• Term: from 2010 to 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 107745057

We will study complex twisted magnetic structures in double exchange-biased heterostructures, where a ferromagnetic layer is sandwiched between two antiferromagnets, exhibiting different Néel temperatures. Rather complex non-collinear magnetic structure can be realized by field cooling and analyzed in detail during different stages of thin film growth and on the fully grown sample by depth-resolved in-situ polarized neutron reflectometry technique and magneto-transport measurements. This system will be extended to thin film systems with Dzyaloshinskii-Moriya interaction supporting magnetic skyrmions, where pinning of skyrmions due to strong exchange bias coupling might appear.
