    Abstract
  • In-situ high pressure behaviors of Jahn-Teller distortions in La0.3Bi0.2Ca0.5MnO3 were studied by energy dispersive X-ray diffraction. External pressure modified effectively local structural parameters such as the MnO bond distance and MnOMn bond angle, and brings about the competition between the distorted mode Q2 and Q3. With pressure increasing, mode Q3 becomes dominant while mode Q2 within the a-b basal plane disappears at ～1.8 GPa.
