Pure and gallium or lanthanum substituted MgCu ferrites, Mg 0.5 Cu 0.5 Fe 2-x M x O 4 (with x = 0 or 0.2 and M = La or Ga) have been prepared by solid state reaction. Sintering experiments were carried out at different temperatures between 900 and 1100Β°C. The phase composition and lattice parameters
