Fig. 4: Bilayer spin polarization is enhanced by spin-orbit coupling.
From: A first-principles study of bilayer 1T'-WTe2/CrI3: a candidate topological spin filter
Left: Collinear PBE+U spin density difference (yellow = positive) sBL − sCrI3 − sWTe2 with an isosurface level value of 0.0025 shows slightly enhanced positive magnetization on the Cr atoms due to spin-polarized charge transfer. Right: Noncollinear PBE+U magnetization density z-component difference (yellow = positive) mBL − mCrI3 − mWTe2 with an isosurface level value of 0.0025 shows more drastic Cr magnetization enhancement, and additionally magnetic induction in WTe2.
