The investigation of the Faraday effect in DyVO_4-type Jahn-Teller
crystals, containing two Kramers doublets E' and E'' in the low-energy
part of the electron spectrum, is performed. The components of the tensor of
linear magnetooptical effect are obtained in the mean field approximation.
The ionic contributions into the effect are separated, the features of their
temperature dependencies are studied. The estimate of the so-called
crystalline contributions into the Faraday effect is performed. It is shown
that the crystalline contributions increase and can be of the same order as
the ionic one when we approach to the absorption edge.
