摘要

High-resolution thermal expansion and magnetostriction measurements were performed on single crystals of α-RuCl_3 in magnetic fields applied parallel to the Ru-Ru bonds. The length changes were measured in the direction perpendicular to the heneycomb planes. Our data show clear thermodynamic characteristics for the field-induced phase transition at the critical field μ_0H_(c1) = 7.8(2) T where the antiferromagnetic zigzag order is suppressed. At higher fields, a kink in the magnetostriction coefficient signals an additional transition or crossover around μ_0H_(c2) ≈ 11 T. The extracted Gruneisen ratio shows typical hallmarks for quantum criticality near H_(c1) but also displays anomalous behavior above H_(c1). We compare our experimental data with spin-wave calculations employing a minimal Kitaev-Heisenberg model in the semiclassical limit. Most of the salient features are in agreement with each other, however, the peculiar features in the region above H_(c1) cannot be accounted for in our semiclassical modeling and hence suggest a genuine quantum nature. We construct a phase diagram for α-RuCl_3 in a magnetic field along the Ru-Ru bonds, displaying a zigzag ordered state below H_(c1), a quantum paramagnetic regime between H_(c1) and H_(c2), and a semiclassical partially polarized state above H_(c2).
