(a) curve at of an LCMO bridge on STO after overetching (inset: behavior near zero current). (b) Resistance measured as averaged voltage at vs of the same sample.
(a) curve of Ar-etched STO at . (b) plot of the same sample obtained from the curves at .
(a) curve at of an LCMO bridge on STO after overetching and -plasma treatment. The thin lines indicate the voltage limit for the measurement; (b) plot at magnetic field and of the same sample.
curves of an LCMO bridge on STO at (a) in 4-point configuration and (b) in 2-point configuration. Insets show derivatives .
(a) curve of an LCMO bridge on STO at measured in a 2-point configuration. (b) Calculation of the expected Joule heating represented as temperature increase vs applied current .
