Faraday effect in Cd(0.57)Mn(0.43)Te in high magnetic field

摘要

The experimental results of Faraday rotation (FR) measurements in dilute magnetic semiconductors in high magnetic field are presented (Dirac Series--Los Alamos). The magnetic field is produced by an explosive-driven flux-compression generator (150 T). Measurements have been carried with samples of Cd(1-x)Mn(x)Te with x = 0.43 using 633 nm light at liquid helium temperature. The FR increases in such samples when the magnetic field exceeds 60 T. Interband exchange interaction and the direct influence of the external magnetic field on the exchange interaction must be considered to interpret the experimental results.
