Title: Synthesis and characterization of the divalent samarium Zintl-phases SmMg₂Bi₂ and SmMg₂Sb₂

Abstract

Here, single crystals of LnMg₂Bi₂ (Ln = Yb, Eu, Sm) and SmMg₂Sb₂ were synthesized using Mg-Bi metal and Mg-Sb metal fluxes, respectively. The crystal structures are of the CaAl₂Si₂ type with space group P3 m1 (#164, Z = 1): SmMg₂Bi₂ (a = 4.7745(1)Å, c = 7.8490(2)Å), EuMg₂Bi₂ (a = 4.7702(1)Å, c = 7.8457(2) Å), YbMg₂Bi₂ (a = 4.7317(2)Å, c = 7.6524(3) Å), and SmMg₂Sb₂ (a = 4.6861(1) Å, c = 7.7192(2) Å). Heat capacity, electrical transport, and magnetization of all bismuth containing phases were measured. The materials behave as “poor metals” with resistivity between 2 and 10 mΩ·cm. Temperature independent Van Vleck paramagnetism is observed in SmMg₂Bi₂ indicative of divalent samarium (Sm²⁺) ions.

Structure and Properties of Single Crystalline CaMg2Bi2, EuMg2Bi2, and YbMg2Bi2

Journal Article May, Andrew F ; McGuire, Michael A ; Singh, David J ; ... - Inorganic Chemistry

Single crystals of CaMg{sub 2}Bi{sub 2}, EuMg{sub 2}Bi{sub 2}, and YbMg{sub 2}Bi{sub 2} were obtained from a Mg-Bi flux cooled to 650 C. These materials crystallize in the CaAl{sub 2}Si{sub 2} structure-type (P3{bar m}1, No. 164), and crystal structures are reported from refinements of single crystal and powder X-ray diffraction data. EuMg{sub 2}Bi{sub 2} displays an antiferromagnetic transition near 7 K, which is observed via electrical resistivity, magnetization, and specific heat capacity measurements. Magnetization measurements on YbMg{sub 2}Bi{sub 2} reveal a weak diamagnetic moment consistent with divalent Yb. Despite charge-balanced empirical formulas, all three compounds are p-type conductors with Hallmore »« less

Thermoelectric transport properties of CaMg2Bi2, EuMg2Bi2, and YbMg2Bi2

The thermoelectric transport properties of CaMg{sub 2}Bi{sub 2}, EuMg{sub 2}Bi{sub 2}, and YbMg{sub 2}Bi{sub 2} were characterized between 2 and 650 K. As synthesized, the polycrystalline samples are found to have lower p-type carrier concentrations than single-crystalline samples of the same empirical formula. These low carrier concentration samples possess the highest mobilities yet reported for materials with the CaAl{sub 2}Si{sub 2} structure type, with a mobility of {approx}740 cm{sup 2}/V/s observed in EuMg{sub 2}Bi{sub 2} at 50 K.

The magnetic and crystallographic properties of rare earth compounds of the type RMg/sub 2/ were studied. The compounds in which R represents La, Ce, Pr, Nd, Sm and Gd were found to be of the cubic Laves phase structure. The remainder of compounds of this series crystallize in the hexagonal Laves phase structure. For all compounds the lattice constants were determined. Most of these compounds order ferromagnetically at temperatures well below 100 K. Exceptions are LaMg/sub 2/, YbMg/sub 2/ and YMg/sub 2/ which exhibit Pauli paramagnetism, whereas SmMg/sub 2/ and EuMg/sub 2/ order antiferromagnetically.

Higher thermoelectric performance of Zintl phases (Eu _0.5 Yb _0.5 ) _1−x Ca _x Mg ₂ Bi ₂ by band engineering and strain fluctuation

Journal Article Shuai, Jing ; Geng, Huiyuan ; Lan, Yucheng ; ... - Proceedings of the National Academy of Sciences of the United States of America

Significance The search for high-efficiency thermoelectric materials encompasses many classes of semiconductors. Zintl phases are attractive thermoelectric materials for thermoelectric applications. Here, we report the high thermoelectric performance of the rarely studied bismuth (Bi)-based Zintl phases (Eu _0.5 Yb _0.5 ) _1−x Ca _x Mg ₂ Bi ₂ with the record figure-of-merit ZT as high as 1.3 at 873 K. This ZT value is, to our knowledge, the highest ever reported in CaAl ₂ Si ₂ -based structures, especially compared with the best antimony (Sb)-based YbZn _0.4 Cd _1.6 Sb ₂ compound. Because Sb-based Zintl compounds have been studied formore »« less
