  Sn0.8Ag0.2Te is a new superconductor with Tc ~ 2.4 K. The superconducting
properties of Sn0.8Ag0.2Te have been investigated by specific heat measurements
under magnetic fields. Bulk nature of superconductivity was confirmed from the
amplitude of the specific heat jump at the superconducting transition, and the
amplitude is consistent with fully-gapped superconductivity. Upper critical
field was estimated from specific heat and electrical resistivity measurements
under magnetic fields. The Hall coefficient was positive, suggesting that the
Ag acts as a p-type dopant in Sn0.8Ag0.2Te.
