© 2020 American Physical Society. The magnetization process of the breathing pyrochlore magnet CuInCr4S8 has been investigated in ultrahigh magnetic fields up to 150 T. Successive phase transitions characterized by a substantially wide 1/2-plateau from 65 T to 112 T are observed in this system, resembling those reported in chromium spinel oxides. In addition to the 1/2-plateau phase, the magnetization is found to exhibit two inherent behaviors: A slight change in the slope of the M-H curve at ∼85 T and a shoulderlike shape at ∼135 T prior to the saturation. Both of them are accompanied by a hysteresis, suggesting first-order transitions. The theoretical calculation applicable to CuInCr4S8 is also shown, based on the microscopic model with the spin-lattice coupling. The calculation fairly well reproduces the main features of the experimentally observed magnetization process, including a relatively wide cant 2:1:1 phase clearly observed in the previous work [Y. Okamoto, J. Phys. Soc. Jpn. 87, 034709 (2018)JUPSAU0031-901510.7566/JPSJ.87.034709]. The robust 1/2-plateau on CuInCr4S8 seems to be originated from the dominant antiferromagnetic exchange interactions and the strong spin-lattice coupling.
