Abstract
This letter reports our experimental results on magnetic-field-induced aftereffects in solution derived Bi4Fe2TiO12 film, in which e' decreases as much as 600 times after treated in a 5T magnetic field as that of the pristine one. The phenomena are explained by an unusual spin-orbital coupling in film, where strong magnetic field provides drive force for spin polarized electrons of electrode to enter film, so as to form a ferromagnetic orbital state, increase the relaxation time of defect dipoles and then produce giant magnetodielectric effects. This process is reversible just by applying a opposite 0.5T magnetic field. Our findings have potential applications on magnetic fabrication of nanopatterns somehow to evade nanohazard, as well as on integraged phononic or photonic crystals on chip.
