The dc voltage arising on epitaxial thin films of rare-earth manganites upon microwave pumping under ferromagnetic resonance conditions has been studied. The temperature dependence of the effect , including the vicinity of the phase transition, is investigated for the first time. The coefficient of the anisotropic magnetoresistance in the manganite under study is shown to be negative; it decreases sharply with approaching the Curie point and vanishes in the paramagnetic phase.
