La 0.67 Ca 0.33 MnO 3 (LCMO)/YBa 2 Cu 3 O y (YBCO)/Ni trilayers were fabricated with varying thickness of the midsuperconducting YBCO layer. Two different deposition systems were used to avoid oxidation of the magnetic metal Ni and contamination of the deposition systems. Transport properties show t
A systematic investigation of lanthanum-based manganite, La 0.67 Ca 0.33 MnO 3 , has been undertaken with a view to understand the influence of varying crystallite size, in the nanoscale, on various physical properties. The materials were prepared by the sol-gel route by sintering at four different
