摘要：

EuBa2Cu3O7-delta (Eu123) and EuBa2Cu4O8 (Eu124) films oriented in c-axis were deposited on SrTiO3 (100) substrates with eutectic NaOH-KOH flux at 450 degrees C. Synthesized phase has changed by using various types of barium source materials. Pure Eu124 films showed superconducting transition at similar to 70 K, zero-resistance was not observed for Eu123/124 two-phase films. One of the possible reasons of this is Eu/Ba substitution of Eu123 phase. According to T-c of the Eu124, the molten hydroxide method enables to deposit high-quality Eu124 films. (C) 2015 The Authors.
