Cross-sectional TEM images of BZO-doped SmBCO films fabricated by LTG technique (LTG- film) on MgO (100) substrate. LTG- films were grown at upper layer substrate temperature, , of (a) 920, (b) 860, and (c) .
Irreversibility field lines as a function of reduced temperature for LTG- films grown at (a) for and (b) for . Arrows in Fig. 2(b) indicate respective starting point and ending point of the upturn shift in LTG- films grown at and .
Magnetic field dependence of at 77 K for LTG- films grown at . Applied magnetic field is parallel to the -axis. Arrows indicate ending points of the plateau regions.
Field angular dependence of at 77 K for LTG- films grown at of (a) and (b) under 0.5 to 3 T.
Superconducting transition temperatures and self-field critical current densities for LTG- films grown at .
Magnetic fields at two kinks obtained from irreversibility field line (we defined the magnetic fields at the starting point and the ending point of upturn as and , respectively), , mean diameter, and mean spacing between BZO nanorods calculated from TEM images.
