摘要：

A study is made of phase transitions in doped La0.9Sr0.1MnO3 compounds using combined x-ray, electrical, and magnetic measurements. Structural phase transitions are observed accompanied by a change in the cell volume at temperatures of 100-110 K and 300-340 K. These structural changes are found to be related to different contributions of the rhombic Jahn-Teller Q(2) mode to the formation of the crystal lattice. The structural transition at 100-110 K is accompanied by distinctive magnetic and electrical properties. The data are analyzed in detail. (C) 1999 American Institute of Physics.
