Magnetoresistance enhancement of (LBMO)1-x/(NiO)x composites based on Spin Valves (Paperback) (ISBN-13: 9783668487666)

Master's Thesis from the year 2016 in the subject Physics - Nuclear Physics, Molecular Physics, Solid State Physics, language: English, abstract: The objective of this thesis is to study the structural, electrical and magnetic properties of (La0.7Ba0.3MnO3)1-x/(NiO)x composites, where 0 0) show an obvious knee, which due to the presence of NiO. The temperature dependence of resistivity showed a metallic behavior below the transition temperature Tms and above this temperature, the behavior become semiconducting. There were various mechanisms that governed the conduction above and below Tms. The semiconducting region was characterized by two main conduction mechanisms, the small polaron hopping (SPH) and the variable range hopping (VRH). In the metallic region at T
