  • Abstract
    We report observations of the gyrotropic change in magnetic susceptibility of the Fe3+ electron paramagnetic resonance at 12.037GHz (between spin states |1/2〉 and |3/2〉) in sapphire with respect to applied magnetic field. Measurements were made by observing the response of the high-Q Whispering Gallery doublet (WGH±17,0,0) in a Hemex sapphire resonator cooled to 5 K. The doublets initially existed as standing waves at zero field and were transformed to traveling waves due to the gyrotropic response.
