摘要：
This paper presents a study of the structure of the Nd0.85Ba0.15MnO3 compound and its stability at a reduced oxygen partial pressure. Structural characteristics of Nd0.85Ba0.15MnO3 have been determined by X-ray diffraction. The sequence of phase transformations in the Nd-Ba-Mn-O system as the oxygen pressure decreases from atmospheric to -21 atm has been identified by a static method using a vacuum circulation apparatus.
