中子衍射实验已经进行，以澄清CeP的磁性结构的压力下，使用一个hire-anvil细胞在1.9 GPa以上。研究了2.8GPa下的P-T相图。发现了一些新的相，如在1.9GPa压力下的2+相（↑ ↑ ↓ ° ↑ ↑）。IA型反铁磁结构（↑ ↑ ↓ ↓）分别在1.9和2.2 GPa下低于22.5和45 K时出现。在2.5- 2.8GPa压力范围内观察到波矢k =1/3的相和铁磁相。
Neutron-diffraction experiments have been performed in order to clarify the magnetic structures of CeP under pressures above 1.9 GPa using a sapphire-anvil cell. The P–T phase diagram up to 2.8 GPa has been investigated. Some new phases have been found, for example the phase 2+(↑ ↑ ↓ ↓ ° ° ↑ ↑) under the pressure of 1.9 GPa. Type-IA antiferromagnetic structure (↑ ↑ ↓ ↓) was found below 22.5 and 45 K at 1.9 and 2.2 GPa, respectively. A phase characterized by the wave vectork=1/3 and a ferromagnetic phase were observed in the pressure range 2.5–2.8 GPa.
