Abstract

Semimagnetic semiconductors provide a link between semiconductor physcis and magnetism. This is especially true for the problem of magnetic polarons bound to neutral donors or acceptors, which have recently been found in these compounds. Spectroscopy provides accurate information about the magnetization around impurity centers with small dimensions in the bound carrier orbit. The experimental access to the exchange energy differs for donors and acceptors, and also the orders of magnitude of the obtained quantities (average magnetization, mean number of localized moments involved, exchange energy) are different. Due to the small size of the impurity, magnetic fluctuation effects are noticeable, especially in the high temperature range where the exchange energy does not vanish due to these fluctuations.
