Description
Summary:The high pressure d.c. sputtering method has been used to fabricate (YBa(2)Cu(3)O(7)/Nd(0.67)Sr(0.33 )MnO(3-y))/(n) [(YBCO/NSMO)(n)] superlattices. X-ray analyses show c-axis epitaxial growth on LaAlO(3) (100) substrates. Nd(0.67)Sr(0.33)MnO(3-y) films are strained due to some difference in lattice parameters between substrate and YBCO sublayers. Magnetization measurements done on single NSMO films show ferromagnetic order below 200 K. Magnetic moment measured for the superlattices below superconducting transition show ferromagnetic order and superconductivity. Such a behavior indicates on the co-existence of superconductivity and ferromagnetism in the total volume of heterostructures, where superconductivity is related to the YBCO sublayer and ferromagnetism to the NSMO sublayer
