Abstract
Lambda-cold dark matter is the predominant cosmological model for explaining the evolution of the Universe and its structures on larges scales. However, the composition of dark matter is unknown. This thesis aims to improve the detection prospects of experiments that search for the axion, a promising dark matter candidate, with resonant detectors called haloscopes. To this end: a ferromagnetic axion haloscope experiment was performed, the coupling between magnetic and photonic resonances was explored, the prospect of superconducting cavities was considered and tested, and theoretical work was done on a potential microwave single photon counter to further improve sensitivities.
