High-pressure structure of LaSr2Mn2O7 bilayer manganite

Journal of Physics and Chemistry of Solids 67:9-10 (2006) 2046-2050

Abstract:

The structure of bilayer manganite LaSr2Mn2O7 has been investigated under high pressure using synchrotron and laboratory X-rays in the angle-dispersive X-ray diffraction geometry up to 35 GPa at ambient temperature. The Rietveld refinement results of the powder diffraction data show a crossover between the axial and equatorial Mn-O bond length values and a significant suppression of Jahn-Teller (JT) distortion around 16 GPa. Our results imply that a re-entrant behavior in LaSr2Mn2O7, which shows equality in all the three Mn-O bond length values around 16 GPa similar to ambient conditions, may dramatically alter the orbital ordering. Further, the P-V data for the bilayer compounds indicate that the additional substitution of La³⁺ for Sr²⁺ lowers the bulk modulus and enhances lattice softening. © 2006 Elsevier Ltd.
