Optical properties of the quasi-one-dimensional magnet CeIr<sub>3</sub>B<sub>2</sub>

POSTER

Abstract

We present the optical properties of the quasi-one-dimensional (1D) magnet CeIr3B2 over a broad temperature range covering the ferromagnetic Curie temperature, Tc=41 K. Polarized spectroscopic measurements combined with first principles density functional theory calculations reveal that the optical response is dominated by the light polarization with respect to the direction of the quasi-1D chains. Suppression of the low frequency optical conductivity with decreasing temperature will be explained within the Kondo lattice framework. Moreover, we will also discuss signatures of spin-charge coupling across Tc.
