Fig. 1: Intercalation of FGT with TBA+ molecules and a comparison of the temperature-dependent magnetization.
From: Magnetic properties of intercalated quasi-2D Fe3-xGeTe2 van der Waals magnet

a Atomic scheme of FGT and TBA+ molecules intercalation. b Magnetization vs. Temperature curves for pristine (green) and intercalated (black) FGT. Zero-field-cooled (open symbols) and field-cooled (solid symbols) curves are also shown. The data were taken in the out-of-plane direction.
