Magneto-optical responses of epsilon-near-zero indium tin oxide thin films
We will discuss the magneto-optical effects in indium tin oxide (ITO) thin films possessing the epsilon-near-zero (ENZ) wavelength in the telecommunication band. The Faraday rotation angle and the polar Kerr rotation angle of the ITO films are increased at around the corresponding ENZ and EN-one wavelengths, respectively, demonstrating enhanced MO effects in continuous ENZ materials. We also discuss some potential applications of ENZ-MO materials.
