Query: Hard ferromagnetism down to the thinnest limit of iron-intercalated
  tantalum disulfide   Two-dimensional (2D) magnetic crystals hold promise for miniaturized and
ultralow power electronic devices that exploit spin manipulation. In these
materials, large, controllable magnetocrystalline anisotropy is a prerequisite
for the stabilization and manipulation of long-range magnetic order. Owing to
their inherent structural and compositional diversity, 2D analogues of
transition metal-intercalated transition metal dichalcogenides could serve as
versatile platforms for the study of 2D magnetism and the exploration of new
device schemes. However, strong interlayer bonds in these intercalation
compounds preclude mechanical exfoliation of bulk crystals down to the
atomically thin limit. Here, we demonstrate the preparation of Fe-intercalated
TaS$_2$ by chemical intercalation of van der Waals layered TaS$_2$ crystals. We
find that Fe$_x$TaS$_2$ exhibits hard ferromagnetic behavior down to the
thinnest limit of this intercalation compound (Fe-intercalated bilayer
TaS$_2$), with giant coercive fields up to 3 T. Variable-temperature quantum
transport, transmission electron microscopy, and confocal Raman spectroscopy
measurements shed new light on the coupled effects of dimensionality, degree of
intercalation, and intercalant order/disorder on the magnetic behavior of
Fe$_x$TaS$_2$. More generally, we show that chemical intercalation gives access
to a rich synthetic parameter space for low-dimensional magnets, in which
magnetic properties can be tailored by the choice of the host material and
intercalant identity/amount, in addition to the manifold distinctive degrees of
freedom available in atomically thin, van der Waals crystals.
