Abstract :
Lithium-Titanium-Zinc spinel ferrites are shown to be candidates to replace Mn-Zn or Mn-Mg-Zn ferrites in industrial applications such as television deflection yokes where moderate initial permeability (500 to 1000) but high resistivity (>108Ωcm) are needed. The best compromises are found in the composition range given by 
and 
in the following formula : Li0.5(1+t-z) Znz Mnm Fe2.5(1-0.2z-0.6t-0.4m-ε) Tit O4 where the Iron deficiency ε and the Manganese amount m are chosen in order to avoid any Fe2+formation. Bismuth addition in the range 10-3- 10-2Bi/mole reduces sintering temperature under 1000°C and strongly enhances the final electrical resistivity.
