Abstract

The magnetic structures of the low-carrier-system CeP are investigated under magnetic fields up to 12.5 T with the field H ∥ [11̄0] and up to 14 T with H ∥ [001] by synchrotron X-ray diffraction utilizing the unique relationship between the magnetic structure and lattice modulation in this system. The magnetic phases corresponding to the modulation wave vectors k = 2/11, 2/10, 2/9 and 2/8 are observed at low temperatures. The magnetic phases with k = 2/8 (↑↑○○○○○○ or ↑↑← →←→←→), k = 2/9 (↑↑○○○○○ ○○ or ↑↑←→←→←→←) and k = 2/11 (↑↑○○○○○○○○○) are the new phases under magnetic fields found in the present work. The result demonstrates that magnetic fields play a role similar to high pressure to realize the unique magnetic structure and its multistep change in CeP. This fact indicates the importance of the magnetic polaron effect mediated by the p-f mixing effect in the system.
