Magnetic stripe cards and magnetic recording paper are commonly used in credit cards, identity cards, and transportation tickets. Barium ferrite was used to prepare magnetic inks and the magnetic ink was coated onto the paper substrate to obtain the magnetic papers. The crystal structure of barium ferrite was characterized by X-ray diffraction (XRD) and the magnetic property of barium ferrite was tested by vibrating sample magnetometer (VSM) The performance of the magnetic recording paper and the surface morphology of the coating magnetic layer were also characterized. The results show that the magnetic ink based on barium ferrite with the formula of 41wt% of the barium ferrite powder, 14wt% of polyurethane, 36wt% of solvent and 9wt% of PVP has good printing characteristics and the magnetic recording papers have good performance.
