Abstract

One of the purposes of research into the growth of high quality superlattices is to develop structures applicable in electronic devices, another to study proximity effect between magnetic and superconducting layers. We report here our recent results on structure, transport and magnetic properties of Nd0.5Sr0.5MnO3/YBa2Cu3O7 superlattices. Up to now among manganite/cuprate structures mostly heterostructures with ferromagnetic ground state of manganite were studied. In the bulk form Nd0.5Sr0.5MnO3 compound is charge ordered insulating antiferromagnet. The NSMO/YBCO superlattices were deposited on (110) NdGaO3 and (100) LSAT substrates. Our preliminary results demonstrate significant differences in the magnetic properties of superlattices deposited on NdGaO3 and LSAT substrates.
