Effect of grain size on optical properties of iron oxide nanoparticles
Singh, G.; Jalandhara, D.; Yadav, K. (American Institute of Physics Inc., 2016)In the present paper, iron oxide nanoparticles are successfully synthesized by the sol-gel method. The grain size is varied by sintering the nanoparticles at different temperature 400, 500, 600, 700 and 800 ?C. Field ... -
Effect of sintering temperature on the optical properties of BiFeO3 nanoparticles
Jalandhara, Devender; Singh, Gurdhir; Yadav, Kamlesh; Jalandhara, D.; Singh, G.; Yadav, K. (American Institute of Physics Inc., 2016)BiFeO3 is a multiferroic material which exhibits excellent optical properties. BiFeO3 nanoparticles are synthesized by using sol-gel method. The prepared samples are sintered at 500?C, 600?C, 700?C, 800?C and 850?C. In ... -
Effect of Ti4+ doping on magnetic properties of charge ordered Bi0.3Ca0.7MnO3
Yadav, Kamlesh; Singh, M. P.; Razavi, F. S.; Varma, G. D.; Yadav, K.; Singh, M.P.; Razavi, F.S.; Varma, G.D. (Institute of Physics Publishing, 2017)The effect of Ti doping in Bi0.3Ca0.7Mn1-xTixO3 (where x = 0.0, 0.015, 0.03, 0.05, 0.08, 0.12 and 0.16) on structural, magnetic and transport properties have been studied. The charge-ordering temperature (TCO) decreases ... -

Thakur, Anjna; Thakur, Priya; Yadav, Kamlesh; Thakur, A.; Thakur, P.; Yadav, K. (American Institute of Physics Inc., 2016)In this paper, poly (ethyl methacrylate) (PEMA) and (PEMA)0.85/(ZnO)0.15 nanocomposite films for 2, 3, 4 and 5 minutes have been deposited by spray pyrolysis technique on indium tin oxide (ITO) coated substrate. The effect ... -
Thickness-dependent magnetic and transport properties of La0.5Sr0.5MnO3 thin films deposited by DC magnetron sputtering on the LaAlO3 substrate
Yadav, Kamlesh; Singh, H. K.; Maurya, K. K.; Varma, G. D.; Yadav, K.; Singh, H.K.; Maurya, K.K.; Varma, G.D. (Springer Verlag, 2018)Thickness-dependent structural, magnetic and transport properties of La0.5Sr0.5MnO3 (LSMO) thin films have been studied. A series of the LSMO films with thickness 30, 60, 125 and 300?nm have been deposited on the LaAlO3 ...
