Abstract

Measurements of DC magnetization, AC susceptibility and Hall effect of $Pr_{0.7}Sr_{0.3}MnO_3$ single crystal are reported. The various features are discussed in terms of competing electronic and spin ordering phase transitions, in particular concerning the $e_g$ and $t_{2g}$ competition and its effect on spin ordering.
