By the multiple reflections and transmissions in a dielectric on a ferromagnetic metal. color and Kerr rotation correlate with each other. It is revealed that the real refractive index of dielectric plays a major role on the variations of color and Kerr signal. while the absorbing term adjusts the intensive color exhibition and Kerr enhancement at much thinner dielectric thickness. https://www.bekindtopets.com/super-pick-Rx-Quadruple-Topical-Ointment-Quadritrop-for-Dogs-Cats-30-mL-super-grab/
