Journal ArticleDOI
Rietveld analysis of XRD patterns of different sizes of nanocrystalline cobalt ferrite
Lawrence Kumar,Lawrence Kumar,Pawan Kumar,A. Narayan,Manoranjan Kar,Manoranjan Kar,Manoranjan Kar +6 more
TL;DR: In this paper, the distribution of cations among the two interstitial sites (tetrahedral and octahedral sites) has been estimated by analysing the powder X-ray diffraction patterns by employing Rietveld refinement technique, and the results reveal the existence of samples as a mixed type spinel with cubic structure.
Journal ArticleDOI
Influence of Al3+ion concentration on the crystal structure and magnetic anisotropy of nanocrystalline spinel cobalt ferrite
Lawrence Kumar,Manoranjan Kar +1 more
TL;DR: In this paper, the crystal structure and phase purity were studied by powder X-ray diffraction (XRD), all the XRD patterns have been analyzed by Rietveld refinement technique using the F d 3 ¯ m space group.
Journal ArticleDOI
Catalase Activity in Leaves and Cotyledons During Plant Development and Senescence1)1) Part X of the series "Studies on Leaf Senescence". Supported in part by a Grant from the Council of Scientific and Industrial Research, Government of India to D.M.
TL;DR: The decrease in the catalase activity during senescense has some functional significance and the drift in the CATALase activity can be taken as a reliable indicator of senescence.
Journal ArticleDOI
Effect of La3+ substitution on the structural and magnetocrystalline anisotropy of nanocrystalline cobalt ferrite (CoFe2−xLaxO4)
TL;DR: In this paper, the saturation magnetization, coercivity and magnetocrystalline anisotropy constants increase with the increase of crystallite size and saturation magnetisation has been analyzed by the Law of Approach (LA) technique.
Journal ArticleDOI
Cation distribution by Rietveld technique and magnetocrystalline anisotropy of Zn substituted nanocrystalline cobalt ferrite
TL;DR: In this paper, the crystal structure and phase purity of powder X-ray diffraction (XRD) method by employing Rietveld refinement technique were studied by powder XRD method.
