| 摘 要： | Two groups of coated conductor samples with different thicknesses of CeO2 cap layers deposited by pulsed laser deposition （PLD） under the same conditions have been studied. Of them, one group is of CeO2 films, which are deposited on stainless steel （SS） tapes coated by IBAD-YSZ （IBAD-YSZ/SS）, and the other group is of CeO2/YSZ/Y2O3 multilayers, which are deposited on NiW substrates by PLD for the fabrication of YBCO-coated conductor through the RABiTS approach. YBCO film is then deposited on the tops of both types of buffer layers by PLD. The effects of the thickness of the CeO2 film on the texture of the CeO2 film and the critical current density （Jc） of the YBCO film are analysed. For the case of CeO2 film on IBAD-YSZ/SS, there appears a self-epitaxy effect with increasing thickness of the CeO2 film. For CeO2/YSZ/Y2O3/NiW, in which the buffer layers are deposited by PLD, there occurs no self-epitaxy effect, and the optimal thickness of CeO2 is about 50 nm. The surface morphologies of the two groups of samples are examined by SEM.

| Abstract: | Two groups of coated conductor samples with different
thicknesses of CeO2 cap layers deposited by pulsed laser
deposition (PLD) under the same conditions have been studied. Of
them, one group is of CeO2 films, which are deposited on
stainless steel (SS) tapes coated by IBAD-YSZ (IBAD-YSZ/SS), and
the other group is of CeO2/YSZ/Y2O3 multi-layers,
which are deposited on NiW substrates by PLD for the fabrication
of YBCO-coated conductor through the RABiTS approach. YBCO film
is then deposited on the tops of both types of buffer layers by
PLD. The effects of the thickness of the CeO$_{2}$ film on the
texture of the CeO2 film and the critical current density
(Jc) of the YBCO film are analysed. For the case of
CeO2 film on IBAD-YSZ/SS, there appears a self-epitaxy
effect with increasing thickness of the CeO2 film. For
CeO2/YSZ/Y2O3/NiW, in which the buffer layers are
deposited by PLD, there occurs no self-epitaxy effect, and the
optimal thickness of CeO2 is about 50nm. The surface
morphologies of the two groups of samples are examined by SEM. |
