Cu₃PdN has been predicted to be a topological semimatal in recent years. The epitaxial thin film growth tehnology of Cu₃PdN films has been successed in 2017. some properties of Cu₃PdN films have been meusured but evidences of Cu₃PdN to be a topological semimatal were not reported.Ofcourse the band structure can be observed by ARPES measurement, but we prefer to all electronic measurement to find evidences, who's method or structure can be used to be some topological material based devices. In this research Cu₃PdN/NbN epitaxial hetero structures were made and some in-plane electronic and magnetic properties ware measured which could open a stage for other researchers to study on this system.
