We studied the normal state magnetoresistance of underdoped superconducting epitaxial Sr1-xLaxCuO2 thin films by applying a high magnetic field up to 22 T parallel to the CuO2 planes and by varying the orientation of a field of given intensity in order to probe the underlying spin system. This infinite layer compound which has the simplest structure of all the cuprates presents a monotonic negative in-plane magnetoresistance with an anisotropic angular dependence which depends on the doping level [1] and on the field intensity [2]. Angular dependence of the in-plane magnetoresistance at highest magnetic fields is the same for films with different doping levels [2]. We compare our observations with the corresponding ones for the other electron-doped family Ln2-xCexCuO4 (Ln=Nd, Pr, La) and we attribute them to a manifestation of antiferromagnetism which appears to be only due to spins in the CuO2 planes.
