Cooperative ordering of superparamagnetic ZnO nanograins
B. Ghosh, M. Sardar, S. Banerjee
In this paper we have tried to understand the precise nature of magnetism in ZnO nanoparticles. Cooling field dependence of magnetic hysteresis and coercive field was observed for…
Enhanced magnetism, memory and aging in Gold-Iron oxide nanoparticle composites
S. Banerjee, S. O. Raja, M. Sardar +3
In this report we present systematic magnetic studies of pure iron oxide nanoparticles and gold iron oxide nanocomposite with increasing Au particle size/content. For the magnetic…
Change in the room temperature magnetic property of ZnO upon Mn doping
S. Banerjee, K. Rajendran, N. Gayathri +3
We present in this paper the changes in the room temperature magnetic property of ZnO on Mn doping prepared using solvo-thermal process. The zero field cooled (ZFC) and field coole…
Enhancement of ferromagnetism upon thermal annealing in pure ZnO
S. Banerjee, M. Mandal, N. Gayathri +1
We report here enhancement of ferromagnetism in pure ZnO upon thermal annealing with the ferromagnetic transition temperature Tc above room temperature. We observe a finite coerciv…
