The present work explores growth, effect of doping magnetic materials (Mn, Co, Ni) in to the host semiconducting material and its electronic properties. The main results of this work include (i) an exhaustive study on the Rietveld analysis to analyze the structure properties of the material by X-ray powder diffraction data. (ii) The topology of the charge density in the crystal analyzed for the understanding the expansion and contraction of the atoms in doped magnetic material. (iii) the high resolution electron density studies carried out by MEM (maximum entropy method) to reveal infinitive information on their magnetic behavior. (iv) the local and average structures from atomic pair distribution function (PDF).
