The entire magnetization process in the two-leg organic spin ladder BIP-TENO is studied with an ultrahigh magnetic field of up to 150 T. Nontrivial multiple magnetization plateaus are observed, indicating there exist strong quantum correlations between spins. In addition to the previously reported 1/4 plateau, another plateau appears at 1/3 magnetization only when spins are decoupled to the lattice degree of freedom in the adiabatic limit. Spontaneous symmetry breaking is expected to occur with the spin-lattice decoupling induced by a fast evolution of external magnetic fields in the range of $\mu$s. Under the adiabatic condition, five fractional (1/4, 1/3, 1/2, 2/3, and 3/4) magnetization plateaus are likely to appear with an assumption that the magnetization saturates at around 160 T.

微秒脉冲兆高斯场诱导的 S=1 有机自旋梯 BIP-TENO 中的亚稳态磁化平台

在高达 150 T 的超高磁场下研究了双腿有机自旋梯 BIP-TENO 中的整个磁化过程。观察到非平凡的多重磁化平台，表明自旋之间存在很强的量子相关性。除了先前报道的 1/4 平台之外，只有当自旋与绝热极限中的晶格自由度解耦时，才会在 1/3 磁化强度处出现另一个平台。由于外部磁场在$\mu$s。在绝热条件下，假设磁化在 160 T 左右饱和，可能会出现五个分数（1/4、1/3、1/2、2/3 和 3/4）磁化平台。
