We report on the magnetic properties of cuprate/manganite bilayers composed of antiferromagnetic (AFM) La2CuO4 and ferromagnetic La0.70Sr0.30MnO3. The temperature dependent magnetization data indicate an interfacial spin-glass state. Furthermore, the bilayer exhibits significant enhancement of coerc...
