Influence of Aluminum Doping on the Magnetic Properties of Li-Zn Spinel Ferrite
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 6
Abstract
Lithium ferrite or doped-lithium ferrite are sustainable and potential magnetic material for the microwave applications. A series of Lithium-Zinc spinel ferrites doped by aluminium having general chemical formula Li0.5(1-x)ZnxFe2.5-yAly- 0.5xO4 with x=0.1 and y = 0.2, 0.4, 0.6 and 0.8 have been synthesized by using precursor citrate sol-gel combustion method. The samples have been subjected to detailed study of magnetic properties. The hysteresis loop of the investigated spinel ferrite sample shows soft ferromagnetic nature. The magnetic parameters such as saturation magnetization, coercivity, remanent magnetization, anisotropy constant, squareness and Bohr Magneton number determined by vibrating sample magnetometer (VSM) measurement. The Curie temperature of the samples decreases with increase in Al3+ concentration.
