Transmission Electron Microscopy Studies on RF Sputtered Copper Ferrite Thin Films
P. D. Kulkarni, S. Prasad, I. Samajdar +2
Copper ferrite thin films were rf sputtered at a power of 50W. The as deposited films were annealed in air at 800°C and slow cooled. The transmission electron microscope (TEM) stud…
Temperature dependence of Magnetic properties in Nanocrystalline copper ferrite thin films
P. D. Kulkarni, Shiva Prasad, N. Venkataramani +5
The copper ferrite thin films have been deposited by RF sputtering at a 50W rf power. The As-deposited films are annealed in air at C and then slow cooled. The As-depo…
The High Field Magnetization in the RF Sputter Deposited Copper Ferrite Thin Films
P. D. Kulkarni, Shiva Prasad, N. Venkataramani +5
Copper ferrite thin films were deposited on amorphous quartz substrates. The as deposited films were annealed in air and either quenched or slow cooled. Magnetization studies were…
Superparamagnetism in Nanocrystalline Copper Ferrite Thin Films
P. D. Kulkarni, R. P. R. C. Aiyar, Shiva Prasad +6
The rf sputtered copper ferrite films contain nanocrystalline grains. In these films, the magnetization does not saturate even in high magnetic fields. This phenomenon of high fiel…
