Abstract:	The spectral and temperature characteristics of the magnetooptical Kerr effect and the optical properties of an La_0.7Ca_0.25Ba_0.05MnO₃ single crystal are studied. The data obtained are used to calculate the components of the permittivity tensor, whose behavior is interpreted within the framework of the known models of the electronic structure of manganites.
