【 摘 要 】

We measured the magnetization and the electric polarization under pulsed magnetic field up to 44 T. In magnetization measurements for H//b∗(perpendicular to the ca-plane), we found a new phase transition through the differential magnetization at 17 T, which is slightly higher than the field range of the magnetization plateau. This finding was supported by the electronic polarization measurements, with the observation of a bump structure in dP/dB signal. These results suggest the new phase transition.
