    We investigated the influence of the BZO nanorods on the surface morphologies of conventional PLD-SmBCO film and the SmBCO film prepared by a low-temperature growth (LTG) technique, developed by us as a novel crystal growth method. Dynamic force microscope (DFM) images showed that growth modes in SmBCO including BZO nanorods films were transformed from spiral growth mode into the 2D nucleation and growth mode. Moreover, observations using the DFM showed growth steps of the PLD- and LTG-SmBCO. Plan-view transmission electron microscope (TEM) images suggested that the BZO pinned the growth of the SmBCO layer.
