Fig. 5: Magnetic anisotropy coefficients for pristine and intercalated FGT.
From: Magnetic properties of intercalated quasi-2D Fe3-xGeTe2 van der Waals magnet

The anisotropy field (black, left y-axis) and the uniaxial anisotropy coefficient (blue, right y-axis) are shown for both pristine (solid symbols) and intercalated (open symbols) in the low-temperature region. It is shown that the anisotropy parameters of FGT decrease noticeably after intercalation.
