Language: English Date of Publication (YYYY-MM-DD): 2002-08-01 Title of Journal: Physical Review B Journal Abbrev.: Phys. Rev. B Volume: 66 Issue / Number: 5 Sequence Number of Article: 054403 Review Status: Peer-review Audience: Not Specified Abstract / Description: We have investigated the Jahn-Teller transition in La1-xSrxMnO3 by high-temperature powder neutron diffraction in the low- doping region (0<x&LE;0.1). The Jahn-Teller transition temperature which is about T-JT&AP;750 K for stoichiometric LaMnO3 is drastically reduced on doping with Sr, becoming T- JT&AP;475 K for x=0.10. The previously identified metrically cubic orthorhombic O phase (Pmnb) for x=0 becomes clearly (also metrically) orthorhombic for small doping x=0.05 and remains so in the doping range investigated. The Jahn-Teller transition is accompanied only by the partial reduction of the distortion of the MnO6 octahedra. From the distortion of the MnO6 octahedra we have determined the orbital mixing coefficients.
