Facile Synthesis, Structure Elucidation, and Magnetic Properties of Perovskite BaTb_1–xBi_xO₃

Abstract

A series of perovskite BaTb1–xBixO3 (0.0 ≤ x ≤ 0.25) solid solutions were synthesized by a typical solid‐state method. Their structures were analyzed by a combination of X‐ray diffraction, neutron diffraction, and selected‐area electron diffraction. All of the materials crystalize in the P1 space group [a = 6.0582(1) Å, b = 6.0473(1) Å, c = 6.0693(1) Å, α = 60.00(1)°, β = 59.84(1)°, γ = 60.06(1)° for x = 0.0 at room temperature]. Magnetic measurements revealed that the magnetic‐ordering temperature decreases with increasing Bi content in BaTb1–xBixO3; therefore, the presence of Bi decreases the magnetic interactions of Tb. Furthermore, the magnetic structure for BaTb1–xBixO3 has been fully described in space group P1.

“…Further studies show that this structural model can be also used to describe the structure of BiFeO 3−δ and BaTbO 3−δ . 21,50,51 However, this P1 space group is not applicable to describe the structure of BaPbO 3−δ at room temperature, which has been confirmed to crystalize in the space group Imma with a ≈ 6.030 Å, b ≈ 8.509 Å, and c ≈ 6.069 Å. 5,[52][53][54] There are four Ba, four Pb, and twelve O in the unit cell of BaPbO 3−δ , where the crystallographically independent Ba, Pb, and O are one, one, and two, respectively.…”

Rare‐Earth Hydroxometalates Ba[RE(OH)5] with RE=Tb, Dy, Ho

“…This hydroxide precursor approach has a clear advantage over syntheses that require temperatures between 800 °C if carbonates or peroxides are used as starting materials, [8] or even more than 2000 °C if only the oxides are used [9] …”

“…This hydroxide precursor approach has a clear advantage over syntheses that require temperatures between 800 °C if carbonates or peroxides are used as starting materials, [8] or even more than 2000 °C if only the oxides are used. [9] Since also oxides with the compositions BaREO 3 [10] and Ba 3 RE 4 O 9 [11] exist in addition to BaRE 2 O 4 , [12] we now targeted precursors with a 1 : 1 ratio of the two metal cations.…”
