Research Area

Sigurd Thienhaus received his diploma in physics at the University of Cologne in 2000 where his studies emphasized magnetoresistive effects in heterostructures of doped manganites.
In summer 2000 he joined the group "Thin adaptive films" at the research center caesar as a PhD student, where he was working on the development of alloys which show shape memory effects and could be used as actuators or sensors. He received his PhD from the University of Bonn at the beginning of 2005.
As a member of the group "Combinatorial Materials Science" his work is now focused on the development of microhotplate arrays and their implementation into combinatorial materials processing. Within a DFG project at the University of Bochum these micro-hotplates will be used for the development of hard magnetic multiphase thin films, so called “exchange spring magnets”.
