| Abstract | Optical manipulation of the magnetic state of matter is a topic of current interest from the fundamental point of view and due to its high relevance in respect to technological applications. Recently we demonstrated that the light resonant with the EuTe bandgap forms long-living spin polaron states associated with the optical excitations. Europium chalcogenides, which include EuTe, are intrinsic magnetic semiconductors. So far, they have been much less explored in respect to optical manipulation of their magnetic state. A possible reason is that they do not show a near-bandgap photolumenescense that is typical of the dilute magnetic material. Here we demonstrate a new approach to the magnetization of a medium by light irradiation. Using a two-colour pump-probe Faraday rotation technique, we demonstrate that in the EuTe at temperature 5K light generates magnetic polarons with a magnetic moment larger than 600 Bohr magnetons. This is about an order of magnitude larger than magnetic polarons arising in diluted magnetic semiconductors. Because of the giant magnetic moment of a polaron, a modest magnetic field of a few tens of mT leads to a full alignment of polarons. To determine how efficiently the light magnetizes the medium we investigate photoinduced magnetic polarons in several europium chalcogenides as a function of pump intensity and temperature. In EuSe and EuO we detected magnetic polarons with an even greater magnetic moment than in EuTe. Moreover, we prove that the density of photoinduced magnetic polarons in EuSe is much larger. The first observation of giant photoinduced magnetic polarons is extremely important not only from the fundamental point of view but also for practical applications. | |||
