Research topic

The research focus is on the development and improvement of magnetic thin films using PVD processes for magnetoelectric composite sensors in the project CRC 1261 - Magnetoelectric sensors: From composite materials to biomagnetic diagnostics. This includes the following topics:

  • Development of new magnetic film processes for magnetic Sensors
  • Development of sputter processes in VONARDENNE CS400S
  • Investigations in deposition behaviors in PVD tools
  • Investigations in ferromagnetic multilayer structures

Short CV

Lars Thormählen received a master's degree in materials science and technology from the University of Kiel in 2017 and afterwards began his doctoral research in thin-film processes and the development of magnetic thin films.
