In this paper, a new two-dimensional antiferromagnetic material, 2D pyrite, was reported, which exhibited a completely planar pentagonal structure. Pentagonal FeS2 were revealed by the first-principles calculation with GGA + U (Ueff = 2 eV) method and proved excellent mechanically stable, ...
Our resultsdemonstrate that the ground state is a q = 0 magnetic structure with spins canting either in or out ofthe kagome plane, giving rise to weak ferromagnetism. We determine the size of ordered momentsand the angle of canting for dif f erent possible q = 0 structures and orbital ...
We report the discovery of an ultra-stable antiferromagnetic two-dimensional (2D) CrF3 phase that is energetically more favorable than the traditionally assumed hexagonal structure. Using first-principles calculations and evolutionary structure searches, we identify a new low-energy rectangular configuration...
Indeed, we have successfully reproduced a linear dispersion relation inherent to the two-sublattice structure, as shown in Supplementary Figure 1. For micromagnetic simulations, we consider 0.4-nm-thick magnetic nanodisks and nanotracks on the sub- strate. With respect to the material parameters, ...
Using our results we explain the collinear AFCI recently found in monolayers of CrO and MoO with charge gaps of 1 and 50 meV 50\,\hbox {meV} , respectively. In addition, we propose bilayers of heavy transition-metal oxides of perovskite structure as candidates to realize a room-temperature ...
Because of this, they are also called phase domain states (the term we use in this review). They are not uniquely distinct because the magneto-crystalline structure of different phase domain states can be matched by a sub-lattice-vector translation. Figure 1c shows the meeting of the so-...
We find an increase in the bias field and a restoration of the reversal via domain nucleation in the trained state. These are identified as plausible results of ion-induced antiferromagnetic ordering with little or no effect on the layer structure. This study demonstrates, therefore, the ...
structure using a scalar-relativistic version of the k-space TB-LMTO method [11] developed in the atomic spheres approximation. We have used two different versions of the generalized gradient approximation (GGA) for the exchange and correlation potential: the Perdew-Wang ...
The phonon structure of antiferromagnetic Bi2Fe4O9 (space group Pbnm No. 55, TN≈240 K) was studied theoretically by calculations of lattice dynamics and experimentally between 10 and 300 K by polarized Raman spectroscopy. Most of the 12Ag+12B1g+9B2g+9B3g Raman modes were unambiguously id...
Fig. 2: All-optical imaging of domain walls in a synthetic antiferromagnet. a Simplified sketch of the scanning-NV magnetometer and the SAF structure. The two magnetic Co layers are antiferromagnetically coupled through the Ru/Pt spacer layer by RKKY exchange interaction. The exact composition of...
