Synthesis and characterization of (La(1-x) Sr(x))2NiMnO6

Mohanty, S (2014) Synthesis and characterization of (La(1-x) Sr(x))2NiMnO6. MSc thesis.



For the last two decades, double perovskite oxides have attracted many researchers as they exhibit interesting properties like multiferroicity. La2NiMnO6 is an example of this type and shows ferromagnetic order near room temperature with high ferromagnetic transition temperature. In the present report, La2NiMnO6 compound has been studied with strontium doping, synthesized through sol-gel route. XRD, resistivity measurements, magnetorestance measurement and UV visible spectroscopy are done. XRD showed the presence of single phase in parent sample and appearance of secondary phase in 20% doped sample. Resistivity verses temperature was plotted to study its electrical behaviour. Graph of ln ñ and temperature inverse were plotted to calculate their activation energies.
