Abstract
Nanocrystalline Ni0.94Co0.03Mn0.04Cu0.03Fe1.96-xAlxO4(x = 0,0.1,0.3,0.5,0.7and0.9) were synthesized using microwave hydrothermal method at 160°C/40 min. The synthesized powders were characterized using XRD, TEM and FTIR. The nanopowders were sintered using microwave sintering method at 950°C/30 min. The prepared samples were characterized using XRD and SEM. The substitution of Al3+ ions in place of Fe3+ ions results decrease of the density and lattice constant. The increase in D.C resistivity and reduction in the initial permeability, Ms and TC has been observed with an increase of Al3+ ions. High D.C resistivity, thereby decrease in the dielectric losses and an excellent temperature stability of Magnetization (4πMs) are desired characteristics of ferrites used for fabrication of microwave devices.
