Abstract
We have deposited epitaxial perovskite heterostructures including nickelates RNiO3 (R=Pr, Nd) on the top of CMR manganites (La1-xPrx)0.7Ca0.3MnO3, (x=0-1) and antiferromagnetic ferrites RFeO3 (R=Nd, Eu). The heterostructures were characterised by XRD, SEM, EDX, HREM, electric and magnetic measurements. Particular attention is paid to the lattice strain in the layers and the structure of their interfaces. A 60 K shift of the metalinsulator transition temperature as well as suppression of the electrical resistivity hysteresis were found for the nickelate film on the ferrite layer. The effects are believed to be due to the strain and magnetic coupling of the layers.
