XPS study of Ni-Fe manganite thermistor material

PDF Version Also Available for Download.

Description

The resistivity of the as-fabricated thermistor material, nickel-iron-manganite, changes during initial aging in the temperature range of 150-300{degrees}C before becoming stable. X-ray photoelectron spectroscopy (XPS) was used to determine if any valency change or chemical shift of the cations or oxygen occurred after aging. The goal of the study was to identify any ionic changes that might affect thermistor stability. The only observed changes in 2p{sub 3/2} peaks due to aging were those related to Ni ions; the same peaks for Mn, Fe, and O remained unchanged. The changes in the Ni 2p{sub 3/2} peak may be related to: (a) ... continued below

The only observed changes in 2p{sub 3/2} peaks due to aging were those related to Ni ions; the same peaks for Mn, Fe, and O remained unchanged. The changes in the Ni 2p{sub 3/2} peak may be related to: (a) the migration of Ni{sup 2+} ions from octahedral to tetrahedral sites, (b) subtle changes in the energy states of Ni{sup 2+} which promoted a more stable ionic structure, and/or (c) the presence of Ni{sup 3+} ions, some of which revert back to Ni{sup 2+}.
