Highly textured $La_{0.7}MnO_{3-\delta}$ films were grown on $LaAIO_3$ (100) substrates for the first time. The films showed a metal-insulator transition at 220 K and exhibited giant magnetoresistance with $\Delta R/R_o = 85\%$ and $\Delta R/R_H > 550\%$. This study demonstrates that the $La_{1-x}MnO_{3-\delta}$ films are unique among the other $La_{1-x}M_xMnO_3$ (M = Ca, Ba, and Pb) thin films showing giant magnetoresistance by virtue of being a self-doped system.
