Microwave Spectroscopy at Low Temperatures and High Magnetic Fields

Several material classes of ongoing research (superconductors, spin systems) are intensively studied with microwave spectroscopy. In this context, we have developed several new microwave probes based on planar microwave transmission lines and resonators. For many material studies we want to apply an external magnetic field, but so far we are limited to field geometries with the magnetic field parallel to the plane of the microwave chip.

Goal of this project is to develop and demonstrate a new measurement layout that features the external magnetic field perpendicular to the microwave chip. This new probe design should then be tested with different microwave chips (metallic and superconducting) and in different setups (magnetic fields up to 8T and temperatures down to 1.5 K).
