Optical properties of diluted narrow band gap magnetic semiconductor nanowire colloids are controlled by modest magnetic elds under 100 Oe. High aspect ratio NiFe2O4 nanowires are used to achieve responsiveness to magnetic eld, light absorption and -scattering. Visible light re ectance of the diluted colloids can be either increased or decreased depending on the nanowire alignment relative to the direction of the light propagation. The prepared colloids can be applied as magneto-optical switches or as smart window devices.
