Abstract :
Simultaneous discharges of Fe and Cu metal sources by thermoionic vacuum arc (TVA) were used as a new procedure for preparation of granular Fe–Cu thin films with sensibly enhanced room temperature giant magnetoresistive effects. The possibilities to produce thin films with a wide range of structural and magneto-transport characteristics are emphasized. The structural aspects of granular Fe–Cu thin films deposited onto Kapton are investigated via X-ray diffractometry, atomic force microscopy and Mössbauer spectroscopy. The magneto-transport properties are strongly related to composition, structure and magnetic interactions inside the films.
