Abstract

We report the discovery of two consecutive, pressure driven magnetic instabilities in Yb2Pd2Sn. They emerge in a non-Fermi liquid environment at the initial and the final point of a dome-like, single magnetic phase at pressures pc11 GPa and pc24 GPa. This singular behavior of Yb compounds is supposed to result from mutually competing, pressure modified energy scales, which in case of Yb2Pd2Sn cause a sign change of the pressure dependence of the Kondo temperature TK and magnetic ordering temperature TN.
