Magnetooptical Kerr rotation and magnetic circular dichroism (MCD) have been measured
in thin epitaxial layers of the narrow gap ferromagnetic semiconductors InMnSb and InMnAs grown
by low-temperature molecular beam epitaxy. The measurements were carried out in the wavelength
range from 400 to 7000 nm. The wavelength dependence of Kerr rotation and MCD were modelled using
the same set of parameters. To calculate the Landau level energies for the above systems we have
used a ![]() |
