“…Sun's group, have done a lot of excellent studies in the antiperovskite compounds, particularly on the NTE properties. Moreover, fascinating properties were also reported in some compositions, such as baromagnetic (Shi et al, 2016), barocaloric effect caused by spin frustration (Matsunami et al, 2015), and large magnetocaloric effect (Sun et al, 2012). Specifically, C. Wang' group have reported a large amount of research work on NTE and MCE in antiperovskite compounds and also thought that lattice entropy is important to be excited due to large negative thermal expansion behavior driven by magnetic effects in the antiperovskite compounds so as to improve the magnetocaloric effect.…”

“…Antiperovskite compounds A 3 BC (A = Fe, Mn; B = Ga, Sn, Cu, Zr, Fe, Co; C = C, N, H) are well-known (Takenaka and Takagi, 2005; Iikubo et al, 2008; Sun et al, 2010a,b, 2012; Song et al, 2011; Wang et al, 2012; Lin et al, 2015; Shi et al, 2016, 2018; Guo et al, 2018) for the rich characteristics of NTE and ZTE, as well as the baromagnetic, and barocaloric properties, though the comprehensive performance of MCE is not as good as the conventional material Gd around room temperature. This material has a very large family, which shows rich magnetic and lattice structure depending on compositions and atomic occupations.…”

Negative thermal expansion (NTE) behaviors in the materials with giant magnetocaloric effects (MCE) have been reviewed. Attentions are mainly focused on the hexagonal Ni2In-type MM'X compounds. Other MCE materials, such as La(Fe,Si)13, RCo2, and antiperovskite compounds are also simply introduced. The novel MCE and phase-transition-type NTE materials have similar physics origin though the applications are distinct. Spin-lattice coupling plays a key role for the both effect of NTE and giant MCE. Most of the giant MCE materials show abnormal lattice expansion owing to magnetic interactions, which provides a natural platform for exploring NTE materials. We anticipate that the present review can help finding more ways to regulate phase transition and dig novel NTE materials.

“…Antiperovskites also show intriguing properties under external fields such as pressure and temperature. Typically, Mn 3 Ga 0.95 N 0.94 was reported to exhibit a remarkable so‐called “baromagnetic effect,” i.e., a magnetic phase transition caused by external hydrostatic pressure. Piezomagnetism was studied theoretically in a series of magnetically frustrated Mn‐based antiperovskite nitrides and experimentally in Mn 3 NiN .…”

ABX3 perovskites, as the largest family of crystalline materials, have attracted tremendous research interest worldwide due to their versatile multifunctionalities and the intriguing scientific principles underlying them. Their counterparts, antiperovskites (X3BA), are actually electronically inverted perovskite derivatives, but they are not an ignorable family of functional materials. In fact, inheriting the flexible structural features of perovskites while being rich in cations at X sites, antiperovskites exhibit a diverse array of unconventional physical and chemical properties. However, rather less attention has been paid to these “inverse” analogs, and therefore, a comprehensive review is urgently needed to arouse general concern. Recent advances in novel antiperovskite materials and their exceptional functionalities are summarized, including superionic conductivity, superconductivity, giant magnetoresistance, negative thermal expansion, luminescence, and electrochemical energy conversion. In particular, considering the feasibility of the perovskite structure, a universal strategy for enhancing the performance of or generating new phenomena in antiperovskites is discussed from the perspective of solid‐state chemistry. With more research enthusiasm, antiperovskites are highly anticipated to become a rising star family of functional materials.

“…The magnetic antiperovskites are typically metallic and often reveal exotic magnetic order [35]. In particular, GaNMn 3 is an itinerant magnetic metal with 5g noncollinear antiferromagnetic ground state [42,43], as shown in Figs. 1(b) and 1(c).…”

“…1(b) and 1(c). Due to the antiferromagnetic (AFM) coupling between Mn atoms on the triangular lattice in the (111) plane, the local magnetic moments of Mn form a clockwise configuration with the angle of 120 • between the directions, canceling the magnetic moments in each plane [42,43]. As the result of this magnetic symmetry, GaNMn 3 is predicted to be piezomagnetic [44,45] and flexomagnetic [46].…”

Using density-functional calculations, we predict the emergence of electrically reversible magnetization at the interface between antiferromagnetic noncollinear antiperovskite GaNMn 3 and ferroelectric perovskite BaTiO 3. We find that Mn magnetic moments are enhanced and reoriented at the GaNMn 3 /ATiO 3 (001) (A = Sr and Ba) interface, resulting in a sizable net magnetization along the [110] direction. This magnetization is reversed with ferroelectric polarization of BaTiO 3 through ∼20 • rotation of the noncollinear magnetic moments. The effect is driven by ferroelectric modulation of the antiferromagnetic exchange coupling between the interfacial Mn atoms mediated by the Mn-3d orbital population. Our results open opportunities for controlling the magnetic properties by electric fields by exploiting noncollinear antiferromagnetism at antiperovskite/perovskite interfaces.
