A transition from large to small polarons in the La0.75Ca0.25MnO3 perovskite system

A quantitative determination of the statistical distribution of the Mn-O instantaneous bond lengths in the La0.75Ca0.25MnO3 system by Mn K-edge extended X-ray absorption fine structure (EXAFS) spectroscopy shows that the giant magneto-resistance (GMR) transition occurs at a crossover from a metallic...
