R Suryanarayanan, V Gasumyants
TL;DR
This paper investigates the magnetotransport properties of Sm0.55Sr0.45MnO3, focusing on Seebeck and Nernst effects under various magnetic fields, revealing that increased carrier density and mobility drive colossal magnetoresistance.
Contribution
It provides new experimental data on thermoelectric coefficients of Sm0.55Sr0.45MnO3 and links these to the mechanisms behind colossal magnetoresistance.
Findings
Seebeck effect varies with temperature and magnetic field.
Nernst coefficient shows field-dependent behavior.
Carrier density and mobility increase contribute to magnetoresistance.
Abstract
Measurements of Seebeck effect in 0 and 1.5 T and Nernst coefficient in 0.3,0.9 and 1.8 T as a function of temperature on a polycrystalline sample Sm0.55Sr0.45MnO3 are presented. The data point out conclusively that an increase inboth the carrier density and the mobility of the charge carriers is responsible for the observed colossal magnetoresistance
