Suppression of photovoltaic effect by magnetic field in Pr0.65(Ca0.75Sr0.25)0.35MnO3/Nb:SrTiO3 heterostructure

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...
