In this paper we show experimental results for the detection of millimeter waves based upon the response of the magnetisation of a material inside a resonator. The experimental evidence is that the magnetisation of the materials shows dramatic changes for the frequencies that match the modes of the resonator-magnetic-material system. The results shown here refer to the use of gadolinium at room temperature and hexa-hydrated iron chloride at low temperature inside a copper loop having resonant frequencies below 20.
