A quasi-two-dimensional antiferromagnet Cs 2 CuBr 4 is characterized as a frustrated spin system on a distorted triangular lattice. 133Cs-NMR experiments on Cs 2 CuBr 4 have been performed in the range of the magnetic field applied along b-axis up to 15.9 T, which covers the field range for the 1 3 magnetization plateau. Field dependence of T 1 - 1 at 0.5 K shows a hysteresis around each end of the plateau, indicating a field induced first order phase transition. We also present NMR spectrum indicating hysteresis and two phase coexistence around the transition field.
