“…These magnetic lms have potential applications in data storage devices, magnetic strips, actuators, magnetic sensors and microwave devices etc. 27,28 Considering the importance of these materials, present study focuses on the detailed understanding of structural, morphological, optical and magnetic properties of N ion implanted CeO 2 thin lms deposited by RF sputtering. This also provides an opportunity to understand the role of defects such as V O and to establish the RTFM in CeO 2 system.…”
