用脉冲激光沉积法从Mo6+态陶瓷靶上外延生长了具有Mo4+态钙钛矿结构的CaMoO3和SrMoO3单晶薄膜。在沉积过程中使用氩气流在几乎晶格匹配的钙钛矿衬底上获得相纯的膜。的薄膜的传输特性是一致的顺磁性和金属相，而剩余的结晶度远低于以前报道的薄膜和散装多晶。这些结果表明，这种生长方法可用于探索在常规氧化气氛中不稳定的4d和5d过渡金属氧化物的界面和结性质。(C)2010日本应用物理学会
Single-crystalline thin films of CaMoO3 and SrMoO3 with a Mo4+ state perovskite structure have been epitaxially grown by pulsed-laser deposition from Mo6+ state ceramic targets. Phase-pure films were obtained on nearly lattice-matched perovskite substrates using argon gas flow during the deposition. Transport properties of the films are consistent with those of paramagnetic and metallic phases, whereas the residual resistivities are far lower than those reported previously for films and bulk polycrystals. These results indicate that this growth method can be useful for exploring the interfaces and junction properties of 4d and 5d transition metal oxides that are unstable in a conventional oxidative atmosphere.
