Superconductivity in dilute alloys of TaS/sub 2/ with Fe

Single crystals of iron-doped Ta${\mathrm{S}}_{2}$ grown from sintered powders of composition ${\mathrm{Fe}}_{0.05}$-Ta${\mathrm{S}}_{2}$ show a rise in critical temperature to above 3 K and an enhanced anisotropy of ${H}_{c2}$ which is comparable to that observed in $2H$-Ta${\mathrm{S}}_{2}$${(\mathrm{pyridine})}_{\mathrm{\textonehalf{}}}$. Single crystals grown from ${\mathrm{Fe}}_{0.05}$${\mathrm{T}}_{0.95}$${\mathrm{S}}_{2}$ powders are stabilized in the $1T$ phase and are semiconducting at all temperatures below room temperature with no resistive anomaly at 200 K.
