The two-dimensional (2D) van der Waals ferromagnetic semiconductors, such as CrI$_3$ and Cr$_2$Ge$_2$Te$_6$, the 2D metals, Fe$_3$GeTe$_2$ MnSe$_2$, have been obtained in recent experiments attracted a lot of attentions. superexchange interaction has suggested to dominate magnetic interactions these systems. In usual theoretical studies, expression Heisenberg models were fixed by hand due exper...

– Magnetic, electric and structural properties of La0.96−yNdyK0.04MnO3+δ with 0≤ y ≤0.4 have been studied experimentally. A disordered magnetic state is formed as La is substituted by Nd, reflecting the competition between ferromagnetic (FM) double exchange and antiferromagnetic superexchange interactions. Key structural parameters are identified and correlated with changes in magnetic and elec...

Recently, great effort has been devoted to the search for two-dimensional (2D) ferromagnetic materials with inherent strong Dzyaloshinskii--Moriya interaction (DMI). Here, through a first-principles approach, we systematically investigate effect of biaxial strain on DMI, Heisenberg exchange interaction, and magnetic anisotropy energy (MAE) Janus Cr$_{2}$X$_{3}$Y$_{3}$ (X, Y = Cl, Br, I, X $\neq...
