We have grown single crystals of Fe1+dTe by a conventional self-flux method.
We obtained plate-like single crystals with dnom \geq 0.1. The value of the
magnetization increased with increasing excess Fe concentration, and a
broadening of the antiferromagnetic transition was observed for dnom >1.15.
Further, we noted that the antiferromagnetic transition of Fe1.134Te (dnom =
0.15) was clearly suppressed to a lower temperature, which would indicate a
possibility of controllability of magnetism by excess Fe concentration.
