Abstract
Mn K-EXAFS measurements of Y0.5Ca0.5MnO3 from 300 K to 120 K show a large static disorder around 160 K, besides significant distortion of the MnO6 octahedron. The average Debye-Waller factor for the MnO octahedral coordination is 0.0025 Å2 in the 160 K region while it is somewhat lower (0.001 Å2) above and below 160 K. These observations are discussed in the light of the structural data as well as the electrical and magnetic properties of this solid.
