- W1777773725 abstract "We present measurements of the magnetic susceptibility $ensuremath{chi}$ and the magnetization $M$ of single crystals of metallic ${mathrm{Yb}}_{2}{mathrm{Pt}}_{2}mathrm{Pb}$, where localized Yb moments lie on the dimerized and frustrated Shastry-Sutherland lattice (SSL). Strong magnetic frustration is found in this quasi-two-dimensional system, which orders antiferromagnetically at ${T}_{N}=2.02text{ }text{ }mathrm{K}$ from a paramagnetic liquid of Yb dimers, having a gap $ensuremath{Delta}=4.6text{ }text{ }mathrm{K}$ between the singlet ground state and the triplet excited states. Magnetic fields suppress the antiferromagnetic (AF) order, which vanishes at a 1.23 $T$ quantum critical point. The spin gap $ensuremath{Delta}$ persists to 1.5 $T$, indicating that dimer singlets survive the collapse of the $B=0$ AF state. Quantized steps are observed in $M(B)$ within the AF state, a signature of SSL systems. Our results show that ${mathrm{Yb}}_{2}{mathrm{Pt}}_{2}mathrm{Pb}$ is unique, both as a metallic SSL system that is close to an AF quantum critical point, and as a heavy fermion compound where quantum frustration plays a decisive role." @default.
