Imaging oxygen defects and their motion at a manganite surface

Published on March 1, 2011

The oxygen migration scenario for electroresistive switching in manganites gets new support. Mobile oxygen adatoms and defects have been observed by scanning tunneling microscopy with atomic resolution at the surface of PrSr2Mn2O7.

Collaboration with UCL/LCN.
