  In the heavy-fermion system $Yb_2Pd_2In_{1-x}Sn_x$, the interplay of
crystal-field splitting, Kondo effect, and Ruderman-Kittel-Kasuya-Yosida
interactions leads to complex chemical-, pressure-, and magnetic-field phase
diagrams, still to be explored in full detail. By using a series of techniques,
we show that even modest changes of parameters other than temperature are
sufficient to induce multiple quantum-critical transitions in this highly
susceptible heavy-fermion family. In particular, we show that, above $\sim 10$
kbar, hydrostatic pressure not only induces an antiferromagnetic phase at low
temperature, but it likely leads to a reorientation of the Yb magnetic moments
and/or the competition among different antiferromagnetic configurations.
