Volume : II, Issue : VIII, September - 2012 Larger Ionic Radii Dependent Properties Of La3+ Substituted Co-cu-cr-fe Nanoparticles Vivek Chaudhari, Sagar E. Shirsath, Maheshkumar L. Mane, R. H. Kadam DOI : 10.9780/22307850, Published By : Laxmi Book Publication Abstract : Nanoparticles of Co Cu Cr La Fe O (x = 0.0, 0.025, 0.05, 0.075, 0.1) 0.7 0.3 0.5 x 1.5-x 4
were synthesized by sol-gel auto combustion method. The synthesized samples were
annealed at 600 ºC for 4 h. X-ray diffraction data were used to evaluate the structure of
the prepared samples. Lattice constant (a), X-ray density (dx), jump length (L and L ), A B
allied parameters were calculated using X-ray diffraction data. Lattice constant and X-
ray density found to increase with La3+ substitution. Ion jump lengths and allied
parameters are increases with the increase in La3+ substitution. The variation of all the
derived parameters are discussed in the light of difference in the ionic radii of La3+ ions
Fe3+ ions. Keywords : Article : Cite This Article : Vivek Chaudhari, Sagar E. Shirsath, Maheshkumar L. Mane, R. H. Kadam, (2012).
