Films of the rutheno-cuprate compound GdSr2RuCu2O8 were grown by on-axis dc sputtering technique, at temperature Ts = 837 °C and in pure oxygen atmosphere. Structural and compositional measurements have been performed on samples prepared on different substrates and at different ex situ annealing procedures. In particular, a detailed analysis of the structure and the local composition of the films have been obtained by high-resolution X-ray diffraction and by energy-dispersive X-ray microanalysis (EDX) of scanning electron microscope (SEM). The films resulted c-axis oriented and single phased. We show the results obtained on a sample deposited on LaAlO3 substrate, (1 0 0) oriented. Magnetic measurements as function of temperature from 1.9 K to 400 K and applied magnetic fields up to 7 T are discussed.

Abstract
Films of the rutheno-cuprate compound GdSr2RuCu2O8 were grown by on-axis dc sputtering technique, at temperature Ts = 837 °C and in pure oxygen atmosphere. Structural and compositional measurements have been performed on samples prepared on different substrates and at different ex situ annealing procedures. In particular, a detailed analysis of the structure and the local composition of the films have been obtained by high-resolution X-ray diffraction and by energy-dispersive X-ray microanalysis (EDX) of scanning electron microscope (SEM). The films resulted c-axis oriented and single phased. We show the results obtained on a sample deposited on LaAlO3 substrate, (1 0 0) oriented. Magnetic measurements as function of temperature from 1.9 K to 400 K and applied magnetic fields up to 7 T are discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
