High-temperature properties of Mn0.75Co2.25BO5 compound
https://doi.org/10.26907/mrsej-24301
Abstract
Temperature-dependence measurements specific heat, thermoelectric power, conductivity, and electron paramagnetic resonance measurements were performed on Mn0.75Co2.25BO5 powder at temperatures above 290 K. Single crystals of Mn0.75Co2.25BO5 were grown by the flux method using Bi2Mo3O12-based solvent diluted with Na2CO3. To investigate EPR and specific heat capacity, the single crystals were ground to powder. The temperature dependencies of the resistance, specific heat, Seebeck constant, and EPR spectra in the range from 290K to 700K were obtained. The transition from the dielectric state to the semiconductor state was detected at 348 K, consistent with the change in the fine structure of the EPR spectrum associated with S = 5/2 for the manganese ion Mn2+.
