Abstract
The temperature dependence of the resistivities of some MnAs1-xSbx and CryMn1-ySb single crystals and polycrystals have been measured for 4. 2 K<T<650 K and different crystal axes. While magnon scattering appear s to be dominant for near-stoichiometric end-member crystals, for mixe d or non-stoichiometric crystals a distinctly different behaviour occu rs which we connect with the occurrence of particular phonon-magnon mi xed modes which appear to be typical for crystals with a random compon ent.
