3d-metal perovskites are promising thin film materials with a great variety of electrical and magnetic properties. We have deposited the epitaxial heterostructures including different combinations of CMR manganites (La1-xPrx)0,7Ca0,3Mn0,3, (x=0-l), metallic nickelates RNiO3 (R=Pr, Nd, Sm) with sharp metal-insulator transition and antiferromagnetic insulators RFeO3 (R=Nd, Eu) . The heterostructures were characterised by XRD, SEM, EDX, HREM, RBS, electric and magnetic measurements. Particular attention is paid to the lattice strain in the layers and the structure of their interfaces. The prototype electronic devices based on the heterostructures are discussed.
