Research ArticleOpen accessElectrical and Magnetoresistive studies Nd doped on La-Ba-Mn-O3 Manganites for Low-field Sensor applicationH. Abdullah, S. A. HalimProblem Statement: Electrical and magnetoresistive properties of the Nd doped (La1-xNdx)0.5Ba0.5MnO3 type samples with 0 ≤ x ≤ 1.0 had been prepared using the solid state reaction. These materials are extensively studied by the substitution of rare-earth compound is to understand the nature of transport phenomena in each system. Approach: The samples were calcined at 900°C for 12 h, pelletized … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,663 accessesView PDF Cite

Research ArticleOpen accessEffect of Divalent Ions (A = Ca, Ba and Sr) Substitution in La-A-Mn-O Manganite on Structural, Magnetic and Electrical Transport PropertiesK. P. Lim, S. W. Ng, S. A. Halim et al.Problem statement: Microstructure of the grain will influence the properties of a polycrystalline manganites when different dopant is introduced. In this work, an effort had been made to investigate the influence of Ca, Ba and Sr substitution in La site. Approach: Polycrystalline manganites compound of La0.67A0.33MnO3 where A = Ba, Sr and Ca had been prepared via conventional solid-state reaction … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 8,253 accessesView PDF Cite
