Abstract
We report the discovery of two consecutive, pressure driven magnetic instabilities in . They emerge in a non-Fermi liquid environment at the initial and the final point of a dome-like, single magnetic phase at pressures GPa and GPa. This singular behavior of Yb compounds is supposed to result from mutually competing, pressure modified energy scales, which in case of cause a sign change of the pressure dependence of the Kondo temperature and magnetic ordering temperature .
