Pressure-Induced Antiferromagnetic Dome in the Heavy-Fermion $Y{b}_{2}P{d}_{2}I{n}_{1-x}S{n}_x$ System

Abstract

In the heavy-fermion system $Y{b}_{2}P{d}_{2}I{n}_{1-x}S{n}_x$, 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.
