Magnetization Process and Collective Excitations in the S=1/2 Triangular-Lattice Heisenberg Antiferromagnet Ba3CoSb2O9

Abstract

We have performed high-field magnetization and ESR measurements on Ba${}_3$CoSb${}_2$O${}_9$ single crystals, as a representative two-dimensional spin-1/2 Heisenberg antiferromagnet on a uniform triangular lattice, and have determined all the magnetic parameters. For an applied magnetic field $H$ parallel to the $ab$-plane, the entire magnetization curve including the plateau at one-third of the saturation magnetization ($M_{\mathrm{s}}$) is in excellent agreement with the results of theoretical calculations except an anomaly near $(3/5)M_{\mathrm{s}}$, indicative of an additional field-induced transition. However, for $H\parallel c$, the magnetization curve exhibits a cusp near $M_{\mathrm{s}}/3$. Paramagnetic resonance signals above the Néel temperature indicate the nearly isotropic $g$-factor. A detailed analysis of the collective ESR modes observed in the ordered state, combined with the magnetization process, provides evidence of the weak easy-plane anisotropy.
