Journal ArticleDOI
Proximity effects induced in graphene by magnetic insulators: first-principles calculations on spin filtering and exchange-splitting gaps.
Hongxin Yang,Ali Hallal,D. Terrade,Xavier Waintal,Stephan Roche,Stephan Roche,Mairbek Chshiev +6 more
TL;DR: First-principles calculations of spin-dependent properties in graphene induced by its interaction with a nearby magnetic insulator (europium oxide, EuO) point toward the possible engineering of spin gating by the proximity effect at a relatively high temperature, which stands as a hallmark for future all-spin information processing technologies.
Journal ArticleDOI
Very large Dzyaloshinskii-Moriya interaction in two-dimensional Janus manganese dichalcogenides and its application to realize skyrmion states
Jinghua Liang,Weiwei Wang,Haifeng Du,Ali Hallal,Karin Garcia,Mairbek Chshiev,Albert Fert,Albert Fert,Hongxin Yang +8 more
TL;DR: In this article, the authors demonstrate that significant DMI can be obtained in a series of Janus monolayers of manganese dichalcogenides MnXY (X/Y = S, Se, Te, X ≠ Y) in which the difference between X and Y on the opposites sides of Mn breaks the inversion symmetry.
Journal ArticleDOI
Anatomy and giant enhancement of the perpendicular magnetic anisotropy of cobalt-graphene heterostructures
Hongxin Yang,Hongxin Yang,Anh-Duc Vu,Ali Hallal,Ali Hallal,Nicolas Rougemaille,Johann Coraux,Gong Chen,Andreas K. Schmid,Mairbek Chshiev,Mairbek Chshiev +10 more
TL;DR: These findings point toward possibilities to engineer graphene/ferromagnetic metal heterostructures with giant magnetic anisotropy more than 20-times larger compared to conventional multilayers, which constitutes a hallmark for future graphene and traditional spintronic technologies.
Journal ArticleDOI
Anatomy of perpendicular magnetic anisotropy in Fe/MgO magnetic tunnel junctions: First-principles insight
TL;DR: In this article, the authors elucidate microscopic mechanisms of perpendicular magnetic anisotropy (PMA) in Fe/MgO magnetic tunnel junctions through evaluation of orbital and layer resolved contributions into the total PMA value.
Journal ArticleDOI
Origin of interfacial perpendicular magnetic anisotropy in MgO/CoFe/metallic capping layer structures.
Shouzhong Peng,Mengxing Wang,Hongxin Yang,Lang Zeng,Jiang Nan,Jiaqi Zhou,Youguang Zhang,Ali Hallal,Mairbek Chshiev,Kang L. Wang,Qianfan Zhang,Weisheng Zhao +11 more
TL;DR: It is found that interfacial PMA in the three-layer structures comes from both the MgO/CoFe and CoFe/capping layer interfaces, which can be analyzed separately, and the variation of PMA with different capping materials is attributed to the different hybridizations of both d and p orbitals via spin- orbits.
