Abstract The applied magnetic field can result in evident changes on the charge-ordering transitions in both Cu-based high Tc superconductors and Mn-based colossal magnetioresistance materials. Alternations of charge modulation and melting of well-defined charge stripes can be commonly observed when the magnetic field is over 2T. We herein present the experimental data obtained in La2CuO4.08 and Pr0.5Sr0.5MnO3 materials, illustrating this kind of interesting phenomena at low temperatures. In particular, some essential structural features alternating along with charge-ordering transition have been discussed.
