Abstract: The heterostructure composed of Pr0.65(Ca0.75Sr0.25)0.35MnO3 and 0.7 wt. % Nb-doped SrTiO3 was fabricated. The heterostructure exhibits an asymmetric current-voltage relation similar to that of p-n junctions and an obvious photovoltaic effect with its maximum value of about 25.1 mV at T = 140 K. It is interesting that the magnetic field has a strong suppression effect on photovoltaic effect, and the maximum relative change of photovoltage under the magnetic field of 1 T is about 63% with the illumination of 15 mW/mm^2 light (532 nm) at T ∼ 140 K. The physical mechanism is explained by the electronic phase separation mechanism.
