Magneto-optical thermal Hall effect — •Annika Ott¹, Philippe Ben-Abdallah², and Svend-Age Biehs¹ — ¹Institut für Physik, Carl von Ossietzky Universität, D-26111 Oldenburg, Germany — ²Laboratoire Charles Fabry, UMR 8501, Institut d'Optique, CNRS, Université Paris-Sud 11, 2, Avenue Augustin Fresnel, 91127 Palaiseau Cedex, France

The control of heat flux at the nanoscale by means of external magnetic fields has attracted much attention, recently. It could be shown that the near-field heat transfer between two magneto-optical slabs can be tuned by the external field [1], and unexpected and very interesting effects like the thermal radiative Hall effect, persistent currents, and giant magneto-resistance [2, 3, 4, 5] have been highlighted. Here we discuss the existence of a circular heat flux [6] as the origin of the thermal radiative Hall effect.
