  Increasing of electronic thermal conductivity of superconductor in the model
with nontrivial density of states was considered. The electronic thermal
conductivity K(T) of SC in the presence of external magnetic field was
investigated. It was shown that if symmetrical part of quasiparticle scattering
rate less than cyclotron energy observed mechanism of increasing K(T) can be
separated from connected with asymmetric electronic scattering effects another
one.
