Abstract
Using the Suhl, Matthias, and Walker two-band model, we have studied the thermomagnetic effects in dirty type-II transition-metal (TM) superconductors, in flux-flow state, immediately below the upper critical field and in the temperature region ${T}_{\mathrm{cs}}^{(0)}<T<{T}_{\mathrm{cd}}(={T}_{c})$. It is found that there is an anomalous increase of $d$-band thermomagnetic effects in dirty TM superconductors below ${H}_{c2}$, arising from the existence of interband impurity scattering. This behavior is analogous to the $d$-band Hall angle, recently investigated by Chow. For pure niobium, our results are exactly reducible to those of Caroli et al. for a one-$d$-band superconductor.
