Large room temperature magnetization in nanocrystalline zinc ferrite thin films
- M. Bohra, S. Prasad, +4 authors R. Krishnan
- Physics
- 29 June 2006
Zinc ferrite films were deposited on fused quartz substrate at different temperatures using pulsed laser ablation (PLA) and rf sputtering. X-ray diffraction indicated that all the films were single… Expand
