Abstract

We have measured the electrical resistivity, the magnetoresistance, the Hall effect, and the magnetization in varying temperature ranges between 0.3 and 300 K on single crystals of (Formula presented) and (Formula presented) The ferromagnetic phase transition of (Formula presented) marked by a sharp peak in the temperature dependence of the electrical resistivity (Formula presented) just below 16 K, is shown to be accompanied by a considerable increase of the effective charge carrier concentration (Formula presented) The overall features of the transport properties of (Formula presented) are similar to those of (Formula presented) A phase transition at 5.3 K has been established. However, the increase of (Formula presented) across this phase transition by two orders of magnitude is much more pronounced than in pure (Formula presented). © 2000 The American Physical Society.
