Single crystal synthesis and magnetism of the BaLn2O4 family (Ln = lanthanide)

Thermochemistry of BaSm2O4 and thermodynamic assessment of the BaO–Sm2O3 system

“…The final single‐phase BaSm 2 O 4 has CaFe 2 O 4 type structure with primitive orthorhombic symmetry (space group Pnma ). The lattice cell parameters from whole profile refinement, a = 10.515(1) Å, b = 12.335(1) Å, c = 3.557(1) Å, are consistent with those previously reported . The stoichiometry of prepared samples is confirmed by wavelength dispersive spectroscopy (WDS) analysis, which yields a BaO:Sm 2 O 3 molar ratio of 0.99 ± 0.05, where the given uncertainty is 2 standard deviations of the mean of 8 measurements.…”

“…Kobayashi et al related this observation to disordering of oxygen vacancies without significant changes on the cation sublattice, although they presented structural data only for room temperature. Recently, Besara et al confirmed the structure from refinements on flux‐grown single crystals, giving unit cell parameters of a = 10.4960 Å, b = 3.5534 Å, c = 12.3129 Å.…”

“…It is rather important to be able to separate the single-ion effects from the collective interactions for the overall understanding of the complex low-temperature magnetic properties of the concentrated strontium rare earth oxides SrR 2 O 4 (as well as the related family of barium rare earth oxides [33][34][35]). We hope that the approach adopted in this paper and that has proven successful for SrEr 2 …”

“…The family of materials AR 2 O 4 (A = Ba, Sr; R = rare earth) [14][15][16] satisfy the two criteria described above. Two crystallographically-inequivalent R sites independently form two different types of zigzag chains [17][18][19] running along the caxis as shown by the schematics in Fig.…”
