Enhanced Curie temperature and skyrmion stability in room temperature ferromagnetic semiconductor CrISe monolayer

Autor: Shen, Zhong, Xue, Yufei, Wu, Zebin, Song, Changsheng

We report CrISe monolayer as a room temperature ferromagnetic semiconductor with the Curie temperature ($T_C$), magnetic anisotropy energy (MAE) and band gap being 322 K, 113 $\mu$eV and 0.67 eV, respectively. The $T_C$ and MAE can be further enhance

Strain-tunable Dzyaloshinskii--Moriya interaction and skyrmions in two-dimensional Janus Cr$_{2}$X$_{3}$Y$_{3}$ (X, Y = Cl, Br, I, X $\neq$ Y) trihalide monolayers

Autor: Shen, Zhong, Song, Changsheng, Xue, Yufei, Wu, Zebin, Wang, Jiqing, Zhong, Zhicheng

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 the effect
