Syntheses, Structures, and Theoretical Studies of New Ternary Antimonides β‐RECoSb₃ (RE = La–Nd, Sm)

Review on crystal structures and magnetic properties of RTX 3 materials

“…RFeSb 3 [61], RNi(Sn, Sb) 3 [62] and RCoSb 3 [63] compounds of the RTX 3 family crystallize in the orthorhombic lattice LaPdSb 3 -type structure with space group Pbcm, similarly to CeCrSb 3 -type structure [54]. A difference between these structure types is two crystallographically inequivalent R atoms in the LaPdSb 3 -type structure and only one crystallographically equivalent R atom in the CeCrSb 3 -type structure.…”

“…Single crystals of RPdSb 3 (R = Ce-Nd, Sm, Gd-Dy) [37], RCrSb 3 [75][76][77][78][79], RVSb 3 [75,80] and RFeSb 3 (R = Pr, Nd, Sm, Gd, and Tb) [61] were synthesized using the liquid self (Sb) flux. Single crystals of RNiSi 3 (R = Gd-Tm, Yb) [41], β-CeNiSb 3 [81], RCoSb 3 (R = Ce, Pr, Nd and Sm) [63], RCrGe 3 (R = Ce, Pr, Nd and Sm) [56]and RNi(Sn, Sb) 3 (R = Pr, Nd, Sm, Gd and Tb) [62] were grown using liquid Sn flux.…”

“…β-CeNiSb 3 [81], RFeSb 3 [61], RNi(Sn, Sb) 3 [62] and RCoSb 3 [63] compounds of the RTX 3 family are reported to crystallize in the orthorhombic lattice LaPdSb 3 -type structure with space group Pbcm. A single crystal study of β-CeNiSb 3 reported to have ferromagnetic ordering below 6 K [81].…”

“…Paramagnetic behavior is reported in single crystals of RNi(Sn, Sb) 3 (R = Pr, Sm, Gd and Tb) [62]. Single crystals of RCoSb 3 (R = Ce, Pr, Nd and Sm) have been reported with only the crystal structure and the magnetic properties of these materials are yet to be reported [63].…”
