Comparison of Effect of Strong Magnetic Field on Microstructure and Photo Absorption Performance of CaTiO₃ and TiO₂

Abstract The study found that after strong magnetic field treatment of CaTiO 3 along with the increase interplanar distance and lattice constant, band gap was reduced photo absorption performance improved. higher applied strength, smaller rutile TiO 2 is, change on constant is nonlinear. before 6T significant, while 9T treatment, light capacity in violet region can be improved effect largely eliminated by simple heat treatment.
