Abstract:
We report synthesis and properties of the ternary Yb compound YbZn2Sb2. The resistivity, magnetization and specific heat at low temperature and high magnetic field of YbZn2Sb2 are typical of a strongly diamagnetic semimetal. A comparison with isostructural YbZn2As2 suggests that YbZn2Sb2 will undergo a nonmagnetic to magnetic quantum phase transition at high pressure that is driven by a valence transition.
