摘要：

YbNiSb has a cubic MgAgAs-type structure and the Yb ions are trivalent. The heat capacity, C, measured in the range 2-20 K is temperature-independent between 2 and 8 K (1.9 J/mol K2) at zero field and shows magnetic field dependence. The value of C/T extrapolated to 0 K is 150 mJ/mol K2. The resistivity (3.6 mOMEGA cm at 300 K) decreases with temperature. These data indicate that YbNiSb is a possible low-carrier heavy-fermion compound.
