Query: Large magnetic anisotropy in $Fe_xTaS_2$ single crystals   In intercalated transition metal dichalcogenide $Fe_xTaS_2$ (0.2 $\leq$ x
$\leq$ 0.4) single crystals, large magnetic anisotropy is observed. Transport
property measurements indicate that heavy Fe-doping leads to a large anisotropy
of resistivity ($\rho$$_{c}$/$\rho$$_{ab}$). A sharp M-H hysteresis curve is
observed with magnetic field along c-axis, while a linear magnetization appears
with magnetic field applied in the ab-plane. The angular dependent magnetic
susceptibility from in-plane to out-of-plane indicates that magnetic moments
are strongly pinned along the c-axis in an unconventional manner and the
coercive field reaches as large as 6 T at T = 5 K. First-principles calculation
clearly suggests that the strong spin-orbital coupling give rise to such a
large anisotropy of magnetism. The strong pinning effect of magnetic moments
along c-axis makes this material a very promising candidate for the development
of spin-aligner in spintronics devices.
