Abstract

The magnetic, electrical and magnetoresistance behavior of Ni doped La2/3Sr1/3Mn1-xNixO3 (0.00 <= x <= 0.09) samples have been studied systematically. Rietveld analysis of XRD shows the formation of pure crystalline phase with rhombohedral symmetry. It has been found that with increasing Ni concentration, magnetization, resistivity, magnetoresistance (MR), Curie temperature (T-c) and metal insulator transition temperature of the samples changes drastically. Doping of Ni at Mn site shows an inverse behavior of %MR at 300 K and 77 K. Further study revealed that all samples show a low field magnetoresistance at low temperature (77 K) which found to increase with the increase of Ni doping. Further, X-ray photoelectron spectrum (XPS) confirms the ionic state of Ni to be Ni2+. In the light of this study, we can say that Ni doped La0.67Sr0.33MnO3 can be synthesized with fine tuning of the dopant ion to bring down T-c further for its application in Magnetic Hyperthermia.
