Electrical and magnetic properties of the spinel-type Li(Ti0.8Cr0.2)2O4

The spinel-type LiTi2O4 exhibits a superconducting transition at 13.7 K. The influence of substitution of Cr3+ ion for Ti at spinel octahedral sites has been remarkably illustrated by previous researchers. The superconductivity is completely destroyed at 2.5% Cr3+ ion by magnetic impurity effect. This short paper will present briefly electrical and magnetic properties of Li(Ti0.80Cr0.20)2O4 at rather high Cr3+ ion substitution.
