    "abstract": "The non-linear relations between polarization strength and electric field\nstrength for ferroelectrics, as well as magnetization strength and magnetic\nfield strength for ferromagnetics, can be achieved by introducing retarded\nelectromagnetic interactions. The electric and magnetic hysteretic loops, as\nwell as polarization and magnetization curves, can be described well based on\nsoft mode theory in the alternating electromagnetic fields of low and medium\nfrequencies. The fundamental phenomenological formula in non-linear optics can\nalso be obtained in high frequency fields. The results show that all of these\nnon-linear phenomena originate from retarded electromagnetic interaction.",
