The corresponding Verdet constant V = $9.5\\times10^{8}$ rad T$^{-1}$m$^{-1}$, exceeds by approximately one order of magnitude that reported in other material systems. Our measurements were conducted at microwave frequencies (f=9.2-11.2 GHz) in a 2DEG with a high dc mobility $\\mu$ = $7\\times10^6$ cm$^2$V$^{-1}$s$^{-1}$, in a hollow waveguide at low-magnetic field (B < 200 mT).
