The Y5−Mg24+(1.08(4)≤x≤1.30(1)) series and a ternary derivative Ce6.9Y12.5(7)Mg92.2: A comparison of their crystal and electronic structures

Study on the evolution of the microstructure, phase composition, three‐dimensional morphology, and hardness in the solution treatment of Mg−7.80Gd−2.43Y−0.38Zr alloy

“…Therefore, the secondary phase can be formulated as Mg 7.22 (Gd, Y), which is significantly different from the previous reports that suggested the secondary phase in the Mg−Gd−Y−Zr series is Mg 24 (Gd, Y) 5 or Mg 5 (Gd, Y) [25–28]. According to the Mg 24+x Y 5−x (1.08≤x≤1.30) series reported by other researchers, the atomic fraction of magnesium in the Mg 24+x Y 5−x series is higher than that of Mg 24 Y 5 or Mg 5 Gd, and the atomic fraction ratio between magnesium and yttrium is close to 7 [29]. Moreover, the x‐ray diffractometry (XRD) pattern of the secondary phase is similar to the Mg 24+x Y 5−x series.…”

Ce11Ge3.73(2)In6.27: Solid-state synthesis, crystal structure and site-preference

“…This type of particular triels substitution, which was confined within the 3-D framework, also resulted in limiting the maximum triels content to six/f.u. in the RE 11 Tt 10 À x In x (Tr ¼ triels) series [2][3][4][5][6]. In addition, given the extra In substitutions for Ge at the Wyckoff 4e, the total number of valence electrons (ve À )/f.u.…”

“…Intermetallic compounds have been an interesting playground for solid-state chemists for decades to explore the relationship between a particular crystal structure and the resultant physical property or vise versa [1][2][3][4][5][6]. Among a vast number of intermetallic compounds, several series of phases adopting the Ho 11 Ge 10 -type structure [6] and carrying the chemical formula of RE 11 Tt 10 À x In x (RE ¼ rare-earth metals; Tt ¼Si, Ge; 2r xr6) [7][8][9][10][11][12] and A 11 Pn 10 À x Tt x (A ¼Rb, Cs, Ca, Sr, Ba, Eu, Yb; Pn ¼Sb, Bi; Tt ¼ Si, Ge, Sn) [13][14][15][16] have been thoroughly studied to assess their potential energy-converting or saving capabilities as magnetocaloric or thermoelectric materials.…”

“…As a result of our continuous investigation for the RE 11 Tt 10 À x In x (RE ¼rare-earth metals; Tt ¼tetrels) systems, we have recently synthesized another isotypic compound of Ce 11 Ge 3.73 (2) In 6.27 including an excess amount of In substitution for Ge in the parental RE 11 Tt 10 À x In x systems [7][8][9][10][11][12]. As reported in many earlier articles, the available anionic sites for the In substitution were known to be confined within the 3-D framework, which also resulted in limiting the maximum In content to six per formula unit (f.u.…”

Crystal Structure, Chemical Bonding and Magnetism Studies for Three Quinary Polar Intermetallic Compounds in the (Eu1−xCax)9In8(Ge1−ySny)8 (x = 0.66, y = 0.03) and the (Eu1−xCax)3In(Ge3−ySn1+y) (x = 0.66, 0.68; y = 0.13, 0.27) Phases

“…Our group has continuously investigated rare-earth metal containing polar intermetallics as well as Zintl phase compounds and successfully synthesized several novel compounds as reported in recent articles [14,15,16,17,18,19,20]. As a part of our ongoing systematic investigations for the Eu-containing polar intermetallic compounds, we attempted to expand the variety of the recently reported (Eu 1− x Ca x ) 9 In 8 Ge 8 series by substituting elements and adjusting reaction conditions.…”
