Oportunities in Joint Research and Development

The research teams of the department can offer joint research in the major research areas mentioned above. Joint research is explicitly offered in following areas:

Development of Data Acquisition systems
Design and realisation of modular measuring systems (PC, VME, or VXI) and distributed laboratory systems using IEEE 488 (GP-IB), RS-232 or USB connection (both hardware and software)

Advanced fluxgate sensors and magnetometers
Although fluxgates may have resolution of 50 pT and absolute precission of 1 nT, their accuracy is often degraded by crossfield response, non-linearities, hysteresis and perming effects. The trends are miniaturisation, lower power consumption and production cost, non-linear tuning and digital processing. Also new core shapes and signal processing methods have been suggested.

Excitation and signal processing of magnetorezistors
AMR and recently also GMR magnetoresistors are the latest competitors of small-size fluxgate sensors. AMR bridges using barber-pole geometry are linear devices; their performance can be improved by periodical flipping. GMR magnetoresistors may be linearized by biasing; we have recently shown that AC bias may decrease their offset, hysteresis and noise.
