Abstract
Faraday rotation of YIG at a wavelength of 1.15 µm was measured at low temperatures in ultra-high magnetic fields up to 350 T generated by an electromagnetic flux compression system, and the spin-flip transition was observed. Exchange parameters Jad= - 25.6 and Jaa=-6.2 cm-1 are deduced from the transition field.
