Abstract :
The results of some measurements on amplitude modulation of 94, 100 and 110 GHz radiation by a magneto-optical effect in a number of magnetic fluids are described. Modulation at frequencies up to 0.25 MHz has been observed, but this may not represent the intrinsic high-frequency cutoff of the effect. The effects of altering both the composition and the concentration of the magnetic fluid are described.
