The search for dark mat­ter is now look­ing at ALPs (ax­ion-like par­ti­cles) as a very promis­ing can­di­date to un­der­stand our uni­verse. Within this frame­work, we ex­plore the pos­si­bil­ity to use NbTi thin film coat­ings on Cu res­onat­ing cav­i­ties to in­ves­ti­gate the pres­ence of ax­ions in the range of 35-45 µeV mass by cou­pling the axion to a very strong mag­netic field in­side the cav­ity, caus­ing its con­ver­sion to a pho­ton which is sub­se­quently de­tected. In this work the chem­i­cal treat­ments and DC mag­netron sput­ter­ing de­tails of the prepa­ra­tion of 9 GHz, 7 GHz, and 3.9 GHz res­o­nant cav­i­ties and their qual­ity fac­tor mea­sure­ments at dif­fer­ent ap­plied mag­netic fields are pre­sented.
