Abstract

Lanthanum strontium manganite microelectrodes with the nominal composition of (La_0.75Sr_0.25)_0.95 MnO₃ and a thickness of ca 500 nm was electrochemically characterized in situ at temperatures from 660 to 850°C using a controlled atmosphere high temperature scanning probe microscope. Impedance spectroscopy and cyclic voltammetry were performed on electrodes with diameters of 20-100 μm in oxygen, air and nitrogen both at open circuit voltage and at anodic and cathodic polarization. In situ conductance mapping, ex situ surface analysis by time-of-flight secondary ion mass spectrometry, and scanning electron microscopy were performed to observe electrical, chemical and structural changes on the microelectrodes.
