Towards Spin Triplet Superconducting junctions in a Dynamic Regime

Master thesis | Physics (MSc)

In an effort to control triplet superconductivity in ferromagnetic disks with RF signals a setup was built to support high frequency experiments in a vector magnet cryostat. This setup included the fabrication of on-substrate coplanar waveguides which can be used to couple RF signals to existing devices by fabricating the devices on top of the waveguide. Another component is the addition of a shielding box which can both block low frequency resonances and can make connecting to the on-substrate waveguides more convenient and reliable. To test the setup, ferromagnetic resonance experiments were done on permalloy thin films using a vector network analyser in addition to the vector magnet.
