“…The averaged magnetization within 25−37 T is about 0.8 μ B /Ni, close to 1/3 of the saturated moment of 2.13 μ B /Ni with g ab = 2.13 (see below) and S = 1. This is a sign of 1/3 magnetization plateau, similar to reports in Ba 3 TSb 2 O 9 (T = Mn, Ni, and Co), 30,31 RbFe(MoO 4 ) 2 , 18,27 and CsFe(SO 4 ) 2 . 18 Accordingly, the possible spin structures within various magnetic-field ranges are also shown in Figure 5.…”

We synthesized a single crystal of K 2 Ni(SeO 3 ) 2 (S = 1) with an equilateral triangular lattice (space group R-3m). The magnetic susceptibility χ(T) and heat capacity C p (T) show that the compound is antiferromagnetically ordered at T N ≈ 7 K. The Curie−Weiss temperature is about θ CW = −72.41 and −71.83 K when the field is applied along the ab plane (H//ab) and parallel to the c axis (H//c), respectively, indicating a strong geometric frustration (f ≈ 10). Both the χ(T) and M(H) point to the presence of easy-plane anisotropy. Density functional theory (DFT) calculations estimate the intraplane exchange (J/k B = −19.04 K) and the interplane exchange (J′/k B = −0.01 K), proving the excellent two-dimensionality. The 50 T high-field magnetization M(H) at 2 K indicates a sign of 1/3 magnetization plateau. The high-field electron spin resonance demonstrates the antiferromagnetic resonance modes with easy-plane anisotropy, yielding J highly consistent with the DFT result. Thus, K 2 Ni(SeO 3 ) 2 is a perfect triangular-lattice antiferromagnet with strong frustration and easyplane anisotropy.

Triple perovskites have garnered research interest in recent years because of their diverse physical properties. This review article delves into the significance of triple perovskite oxides, an important variant of ABO 3 -type perovskites. It provides a comprehensive overview of recent advancements in understanding these A 3 B 3 O 9 /A 3 BB 2 ′O 9 oxide materials, emphasizing their chemical structure and its interplay with diverse properties such as magnetic and electric behaviors. A new framework is proposed to distinguish these functional materials from the other perovskite variants. In addition, the article explores potential technical applications including renewable energy devices, thermistors, optoelectronics, and triboelectric nanogenerators within the perovskite family.
