Hole-doped La_{2/3}Ba_{1/3}MnO_{3} (LBaMO), La_{2/3}Ca_{1/3}MnO_{3} (LCaMO) and La_{2/3}Ce_{1/3}MnO_{3} (LCeMO) thin films were grown heteroepitaxially on 0.1 wt.% Nb-doped SrTiO_{3}(100) (STON) substrates by magnetron sputtering. The prepared LBaMO/STON, LCaMO/STON, LCeMO/STON heterostructures demonstrated nonlinear rectifying current-voltage characteristics. Negative magnetorestance values have been indicated at low bias, meanwhile bias-dependent magnetoresistance has been measured at positive bias voltage values U > U_d where U_d is the interfacial potential, corresponding to a steep current increase at a forward bias.
