Abstract

Magnetic oxide superlattice are attractive model system for the study coupling and interface effects.We report on the growth, structural and magnetic characterization of Nd0.81Sr0.19MnO3/YBa2Cu3O7 (NSMO/YBCO) multilayers. NSMO system for the doping level x=0.19 is a ferromagnetic insulator with Curie temperature of about 100 K. Multilayers with fixed NSMO thickness of 13 unit cell and varying YBCO layer thickness for 2 unit cell to 6 unit cell were sputtered on LaAlO3 substrates. Hysteresis loops measured above and below superconductivity transition show a signature of interlayer coupling
