Magnetic Phase Transition and Magnetization Plateau in Cs_2CuBr_4

概要

• 論文の詳細を見る

• The crystal structure of Cs_2CuBr_4 is the same as that of Cs_2CuCl_4, which has been characterized as a spin-1/2 quasi-two-dimensional frustrated system. The magnetic properties of Cs_2CuBr_4 were investigated by magnetization and specific heat measurements. The phase transition at zero magnetic field was detected at T_N 1.4 K. It was observed that the magnetization curve has a plateau at about one-third of the saturation magnetization for magnetic field H parallel to the b- and c-axes, while no plateau was observed for H || a. The field-induced phase transition to the plateau state appears to be of the first order. The mechanism leading to the magnetization plateau is discussed.
