It was recently demonstrated that the anisotropic phonon heat transport behavior is a good probe of the stripe formation in La2-xSrxCuO4 (LSCO) [X. F. Sun et al., Phys. Rev. B 67, 104503 (2003)]. Using this probe, we examined an electron-doped cuprate Pr1.3-xLa0.7CexCuO4 (PLCCO) and found that essentially the same features as those in LSCO are observed. Moreover, the in-plane resistivity rho(ab) of lightly doped PLCCO shows metallic behavior (drho(ab)/dT>0) in the Neel ordered state with a mobility comparable to that in LSCO. It is discussed that these peculiar properties in common with LSCO signify the existence of stripes in electron-doped cuprates.
