“…It should be noted that the obtained occupancy values of Mn Mn and Mn Sb are consistent with the reported data in the literature. 23,31,32,34,35 The contents of Mn Mn and Mn Sb are estimated also by fitting the magnetic susceptibility (Figure 3b) in the paramagnetic region using the FIM model (eqs 1 and 2). Based on Curie parameters C A and C B , the values of x and y are calculated as shown in Table S2 and Figure S7.…”

The intrinsic magnetic topological materials Mn(Sb/Bi)2n+2Te3n+4 have attracted extensive attention due to their topological quantum properties. Although, the Mn–Sb/Bi antisite defects have been frequently reported to exert significant influences on both magnetism and band topology, their formation mechanism and the methods to manipulate their distribution and concentration remain elusive. Here, we present MnSb2Te4 as a typical example and demonstrate that Mn–Sb antisite defects and magnetism can be tuned by controlling the crystal growth conditions. The cooling rate is identified as the primary key parameter. Magnetization and chemical analysis demonstrate that a slower cooling rate would lead to a higher Mn concentration, a higher magnetic transition temperature, and a higher saturation moment. Further analysis indicates that the Mn content at the original Mn site (MnMn, 3a site) varies more significantly with the cooling rate than the Mn content at the Sb site (MnSb, 6c site). Based on experimental observations, magnetic phase diagrams regarding MnMn and MnSb concentrations are constructed. With the assistance of first-principles calculations, it is demonstrated that the Mn–Sb mixing states primarily result from the mixing entropy and the growth kinetics. The present findings offer valuable insights into defects engineering for preparation of two-dimensional quantum materials.

“…In this work, we systematically investigate the magnetic properties of MnBi 4 Te 7 and MnBi 6 Te 10 thin flakes down to 1-SL by employing polar reflective magnetic circular dichroism (RMCD) spectroscopy. We demonstrate that the odd-even-layer oscillation of compensated and uncompensated AFM states, a common effect in ideal Atype AFM materials [12,[30][31][32], vanishes in atomically thin MnBi 4 Te 7 and MnBi 6 Te 10 . In all the measured samples above 1 SL, in addition to the AFM spin-flip transition, a significant FM hysteresis loop centered at zero field is observed.…”

“…As a close relative to MnBi 2 Te 4 /(Bi 2 Te 3 ) n family, MnSb 2 Te 4 /(Sb 2 Te 3 ) n family remains relatively less explored. The Weyl semimetal state and highly tunable magnetic properties are confirmed in MnSb 2 Te 4 . − Another highlighted material, MnSb 4 Te 7 , was successfully synthesized by Guo et al, and a huge anomalous Hall conductivity (AHC) was observed in experiments. It is also expected to be an antiferromagnetic topological insulator and an axion insulator simultaneously in its magnetic ground state.…”
