Ferromagnetism and spin polarized charge carriers in In$_{2}$O$_{3}$ thin films (2008)
Panguluri, Raghava P., Kharel, P., Sudakar, C., Naik, R., Suryanarayanan, R., Naik, V. M., ...
We present evidence for spin polarized charge carriers in In$_2$O$_3$ films. Both In$_2$O$_3$ and Cr doped In$_2$O$_3$ films exhibit room temperature ferromagnetism after vacuum annealing, with a...
Electric field control of magnetic phase transitions in Ni3V2O8 (2007)
Kharel, P., Sudakar, C., Harris, A. B., Naik, R., Lawes, G.
We report on the electric field control of magnetic phase transition temperatures in multiferroic Ni3V2O8 thin films. Using magnetization measurements, we find that the phase transition temperature...

We report a surfactant assisted synthesis of Mn doped ZnO polycrystalline samples showing robust room temperature ferromagnetism as characterized by X-ray diffraction analysis, Transmission Electron...
Nanocomposites containing Fe or FeCo (Fe-rich) dispersed in hexaferrites (M, W, or Y phase) are realized by the heterogeneous solid-gas reduction under H^sub 2^ + N^sub 2^. Transmission electron...
The presence of mesopores in $\gamma-Fe_2O_3$ is a limiting factor for its optimal magnetic properties. Therefore, high coercive $\gamma-Fe_2O_3$ nano-fibrous particles are obtained by coating cobalt...
