“…There is a quasilinear response in all cases at T comp , as observed in Ni 4 Nb 2 O 9 . 25–27 The magnetization cycles measured at 5 K are open for x = 0.05 and x = 0.10, in agreement with the χ ( T ) curves, and the x = 0.05 sample with higher remnant magnetization also exhibits the higher coercive field. This still holds true for x = 0.15, which shows nearly zero magnetization below T comp , and also displays little to no hysteresis in the 5 K magnetization cycle (Fig.…”

“…Ni 4 Nb 2 O 9 is a special case in this series since it is FIM with T N = 77 K, it exhibits magnetization reversal with T comp = 32 K and no LME effect. 25–28 Its crystalline structure is different too, as drawn in Fig. 1(d).…”

“…Then, we measure the magnetization while the temperature is increased. In experiments, Meng et al [13] have implemented the FCW protocol, where after the FCC protocol the negative magnetization is reversed using a high field at a low temperature. In the MF calculations, we compute both protocols by using different initial conditions when solving numerically equation (16), while increasing the temperature.…”

“…In this compound, ferrimagnetism arises due to the balance of two ferromagnetic lattices, corresponding to the two different Ni sites (A and BB), which are antiparallel to each other. The MR is due to the different temperature dependence of the magnetization of the A-layer and BB-layers [13,14]. This system was first studied by Ehrenberg et al [4] using MF calculations, finding a very good description of the MR.…”

The magnetization reversal (MR) of the layered Ni 4 − x Zn x Nb2O9 ferrimagnetic compounds, with x = 0 , 0.25 , 0.50 and 0.75, is studied in this work using Monte Carlo (MC) simulations and mean field (MF) calculations. First, we analyze the parent compound to set the parameters of our simulations; testing together MC simulations, MF calculations, and MR experiments reported by Bolletta et al (2022 J. Appl. Phys. 132 153901). Then using two different approaches we fit the MR curves of the series of compounds finding a quite good agreement between MC simulations and the experiments. According to these results, Zn substitutions change the relative contribution to the magnetization of the different layers. Here we present two possible hypotheses to explain this effect; one involving a heterogeneous distribution of Zn2+ among the layers, and the other related to distortions of the NiO6 octahedra.

“…Ni 4 Nb 2 O 9 also presents the particularity to be ferrimagnetic (FIM) at low temperature, with an in-plane FM arrangement of magnetic moments, aligned along b , and with AFM coupling along c . This material also presents magnetization reversal (MR), which manifests as a crossing of magnetization ( M ) from M > 0 to M < 0 below a compensation temperature ( T comp ), in which the magnetic substructures cancel each other resulting in zero magnetization. − …”

Corundum and related compounds possess interesting properties for functional applications, such as magnetization reversal or linear magneto electricity, depending on their structures and magnetic ground states. In this system, materials corresponding to the A 4 Nb 2 O 9 formula crystallize in two different structures, i.e., Pbcn for Ni 4 Nb 2 O 9 and P3̅ c1 for A = Co, Fe, and Mn, leading to ferrimagnetism and antiferromagnetism at low temperature, respectively. In this family, the nickel-based compound is special because Ni 4 Nb 2 O 9 is the only one crystallizing in the orthorhombic structure. The Pbcn and P3̅ c1 structures are both able to adapt to various substitutions of the A-cation, and as soon as Ni is involved, the two structural types are stabilized depending on the Ni/A ratio and A. In this context, the differences reported in the structural and magnetic behaviors of the Ni 4−x Co x Nb 2 O 9 and Ni 4−x Zn x Nb 2 O 9 series motivated the (Ni/Co/Zn) 4 Nb 2 O 9 study by mapping the magnetization-structure-composition phase diagram. This first step toward compositionally complex materials allows us to identify an unexpected large area of compounds that exhibit ferrimagnetism and magnetization reversal. Moreover, inside this domain, interesting variations of Neél temperature and compensation temperature are observed, including an increase of T comp induced by nonmagnetic substituting cations. The originality of these structural and magnetic behaviors makes these materials promising for theoreticians to provide conceptual models, especially since the partial substitution of the magnetic cation by a d 0 one may enhance the magnetization reversal.
