Electric and magnetic properties of titanium-cobalt-oxide single crystals produced by floating zone melting with light heating

Single crystals of spinel Co₂TiO₄, CoTiO₃ of ilmenite structure and pseudobrookite CoTi₂O₅ were grown by means of zone melting equipment URN-2-ZM. The growth processes were performed in an air atmosphere with a speed ∼10 mm/h and a final annealing of the crystal at temperature of 1250 °C. Co₂TiO₄ an...
