Abstract
We report scanning tunnelling microscopy images of polaronic charge ordered patch on the layered ferromagnet La2−2x Sr1+2x Mn2O7, x=0.32. The spectroscopic investigation shows that the material is gapped above and below the critical temperature, where the gap changes from 500 to 800 mV, giving evidence for polaronic transport behaviour.
