Substituted LiR x Mn 2−x O 4 (R=La 3+ , Ce 3+, Pr 3+ and x=0.00−0.20) nanoparticles are prepared by the sol–gel method and the consequent changes in their lattice structure, dielectric and electrical parameters are determined by XRD, ED-XRF, SEM, LCR meter bridge and dc electrical resistivity measurements. Diffraction data show that the samples...
Spinel lithium manganese oxide, LiMn 2 O 4 and its derivatives are prepared by the sol–gel method. The lattice constant of the pure material is calculated as 8.23Å. Different transition metal cations of chromium, iron, cobalt, nickel, copper and zinc (0.05 and 0.15M) are doped in place of manganese in the LiMn 2 O 4 . X-ray powder diffraction data show that the spinel...
