Anisotropic correlations in higher manganese silicides

Nagendra S. Chauhan et al.

Summary: In this study, the implications of anisotropy on the thermoelectric performance of HMS are investigated. It was found that single crystal specimens exhibited high electrical and thermal conductivity along the c-axis direction, while the maximum Seebeck coefficient was measured along the perpendicular direction. Polycrystalline specimens showed weakened anisotropy with enhanced weighted mobility and reduced thermal conductivity, resulting in a higher thermoelectric figure-of-merit. This study provides new insights into the structure-property relationships and emphasizes the importance of considering anisotropic behavior in HMS crystals.

Inelastic Neutron Scattering Study of Phonon Dispersion Relation in Higher Manganese Silicides

Randy Belanger et al.

Summary: We present the results of inelastic neutron scattering (INS) measurements on the phonon dispersion relation in higher manganese silicides (HMSs). A large single crystal ingot of HMS is synthesized using a slow cooling technique, with Mn15Si26 identified as the primary phase. The sample consists of highly oriented crystallites as confirmed by neutron pole-figure study and thermal conductivity data. Our INS results generally agree with previous experimental and theoretical studies on phonons in HMS; however, we also observe some discrepancies, such as a 5 meV gap at the zone center and a softer dispersion relation for the low-lying twisting mode. We discuss the possible origins of these observations and their implications for the thermal properties of HMS.

Thermodynamic Guidelines for Maximum Solubility

Shashwat Anand et al.

Summary: When synthesizing doped compounds, it is important to accurately predict the changes caused by defects and simplify initial assessments using defect thermodynamics. Graphical guidelines based on stoichiometry of impurity phases can be used to determine the maximum solubility of dopants caused by neutral and charged defects.

Thermoelectric properties of higher manganese silicide consolidated by flash spark plasma sintering technique

Seongho Choi et al.

Summary: Thermoelectric properties of higher manganese silicide were investigated using a combination of ball milling and flash spark plasma sintering (FSPS) technique, and the results were compared to conventional spark plasma sintering (SPS) samples. Despite the short sintering time of less than 50 s, FSPS samples exhibited similar crystallographic and thermoelectric properties to SPS samples with much longer sintering time. Notably, the grain growth was significantly suppressed in the FSPS samples, although it had minor effects on the transport properties.

High temperature oxidation of higher manganese silicides

Antoine de Padoue Shyikira et al.

Summary: The oxidation kinetics and mechanisms of higher manganese silicides were studied, revealing that spark plasma sintering is a better densification method than hot pressing. Doping with 0.5at% Ge resulted in the lowest oxidation rate, attributed to the stable formation of a SiO2 protective layer.
