We report the observation of tunneling anisotropic magnetoresistance in an organic spin-valve-like structure with only one ferromagnetic electrode. The device is based on a unique high-mobility perylene diimide-based n-type organic semiconductor. The effect originates from the tunneling injection from the La0.7Sr0.3MnO3 contact and can thus occur even for organic layers which are too thick to support the assumption of tunneling through the layer. Magnetoresistance measurements show a clear spin-valve signal, with the typical two-step switching pattern caused by the magnetocrystalline anisotropy of the epitaxial magnetic electrode.
