我们进行了磁化测量的S = 3/2的“呼吸”烧绿石反铁磁体LiInCr 4 O 8在磁场高达130 T使用同轴型磁化拾取线圈在水平单匝线圈兆高斯发生器。磁化过程表现出相变到1/2磁化平台阶段，伴随着磁化强度的突然增加，在约100 T处具有可辨别的磁滞。此外，我们还观察到一个肩状行为的磁化过程中之前的1/2平台阶段，暗示存在一种新的磁性相，特有的“呼吸”烧绿石反铁磁体。
We conducted magnetization measurements on an S = 3/2 "breathing" pyrochlore antiferromagnet LiInCr4O8 in magnetic fields of up to 130T using a coaxial-type magnetization pickup coil in a horizontal single-turn coil megagauss generator. The magnetization process exhibits a phase transition to a 1/2-magnetization plateau phase accompanied by a sudden increase in the magnetization with a discernible hysteresis at approximately 100 T. In addition, we also observed a shoulder-like behavior in the magnetization process prior to the 1/2-plateau phase, implicating the existence of a novel magnetic phase, peculiar to the "breathing" pyrochlore antiferromagnet.
