Query: SDW transition of Fe1 zigzag chains and metamagnetic transition of Fe2
  in TaFe$_{1+y}$Te$_3$   We systematically study the AFM order of Fe1 zigzag chains and spin-flop of
excess Fe2 under high magnetic field H through the susceptibility,
magnetoresistance (MR), Hall effect and specific heat measurements in
high-quality single crystal TaFe$_{1+y}$Te$_3$. These properties suggest that
the high temperature AFM transition of the TaFeTe$_3$ layers should be a
SDW-type AFM order. Below T$_N$, Fe1 antiferromangetic zigzag chains will
induce a inner magnetic field \textbf{H$_{int}$} to interstitial Fe2 and lead
Fe2 also forms an AFM alignment, in which the magnetic coupling strength
between Fe1 and Fe2 is enhanced by decreasing temperature. On the other hand,
the external magnetic field \textbf{H$_{ext}$} inclines to tune interstitial
Fe2 to form FM alignment along \textbf{H$_{ext}$}. When \textbf{H$_{ext}$}
arrives at the "coercive" field H$_C$, which is able to break the coupling
between Fe1 and Fe2, these interstitial Fe2 atoms take a spin-flop from AFM to
FM alignment. The local moment of Fe2 is about 4 $\mu_{\textrm{B}}$/Fe. From
low field ($<$H$_C$) AFM to high field ($>$H$_C$) FM for Fe2, it also induces
sharp drop on resistivity and an anomalous Hall effect. The possible magnetic
structure of TaFe$_{1+y}$Te$_3$ is proposed from the susceptibility and MR. The
properties related to the spin-flop of Fe2 supply a good opportunity to study
the coupling between Fe1 and Fe2 in these TaFe$_{1+y}$Te$_3$ or Fe$_{1+y}$Te
with interstitial Fe2 compounds.
