Magnetooptics of Manganites with Collosal Magnetoresistance

Abstract

The determination of trends in the emergence of magnetooptical properties and the influence of magnetic phase transitions on the optical properties of magnetic materials is a topical issue in various areas of physics and engineering. The present review is focused on the high-magnitude magnetooptical effects of magnetotransmission and magnetoreflection of unpolarized radiation in a wide spectral region discovered in manganites with colossal magnetoresistance (CMR). The physical mechanisms of these magnetooptical effects in manganites and the potential for their practical application are discussed. The questions requiring further study are formulated.
