Description	The magnetic, electric, and thermal transport properties of the single-crystal Pr1#xSrxMnO3 perovskites have been investigated in the compositional region 0.48x0.57. The end compositions are characterized as ideal examples of the ferromagnetic (TC = 290 K) and the A-type antiferromagnetic (TN = 215 K) metals with a strong quadratic temperature dependence of the electrical resistivity below TC (TN), respectively. A transient behavior is observed on two intermediate samples with x0.5, which are ferroma gnetic below TC = 265 K and undergo a second transition to antiferromagnetism at TN = 125#155 K. Appreciable magnetoresistance effects in these samples below TN are attributed to the field-induced antiferromagneticferromagnetic phase transition. A detailed comparison of observed magnetothermal and magnetoelectrical conductivities justifies the application of Wiedemann#Franz law and points to an important role of electronic contribution in the thermal transport.
