Abstract
- The structural, electrical, and magnetic properties of lithium zinc ferrite prepared by ceramic technology have been studied. The composition of lithium zinc ferrite is Li<subscript>0.4</subscript>Fe<subscript>2.4</subscript>Zn<subscript>0.2</subscript>O<subscript>4</subscript> with 1 and 2 wt % bismuth oxide. The addition of Bi<subscript>2</subscript>O<subscript>3</subscript> prior to sintering of the samples has been shown to affect the structural, electrical, and magnetic properties of the ferrite. A significant increase in density from 4.47 to 4.65 g/cm<superscript>3</superscript> and a decrease in porosity from 4.8 to 2.3% have been observed when the concentration of bismuth oxide has been increased to 2 wt %. The Bi<subscript>2</subscript>O<subscript>3</subscript>-containing samples have higher specific electrical resistivity compared to that of the additive-free lithium zinc ferrite. The introduction of bismuth oxide has reduced the specific saturation magnetization from 70.55 to 54.76 G cm<superscript>3</superscript>/g. The Curie temperature has not changed significantly. An optimal combination of macroscopic properties of ferrite has been found at 1 wt % Bi<subscript>2</subscript>O<subscript>3</subscript> concentration. [ABSTRACT FROM AUTHOR]
