Research Group on functional thin films

Leader: Prof. Dr. Christian Jooss

Our main research interest is the space resolved investigation of transport and magnetic properties of thin films and their correlation with the crystal and defect structure on different length scales. The following material systems are in the focus of our research:

• High-temperature superconducting films: Development of an understanding of the current transport in HTS on all length scales. Main topics are properties of grain boundaries, vortex pinning, vortex dynamics and the behavior of superconductors in magnetic environments.

• Charge ordered manganate films: Study of the metal insulator transition, electronic phase separation and magnetic properties. Tailoring of the MI transition by controlling the defect formation and sample dimensions on the nanoscale. This work is part of the SFB 602.

• Ferromagnetic thin films: Growth and patterning of hard and soft magnetic thin films. Development of a full quantitative spatial imaging of magnetization distributions. Realisation of nanopatterned hard magnetic films.
