Abstract

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⁺ (↑↑ ↓↓ οο ↑↑) 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 vector k = 1/3 and a ferromagnetic phase were observed in the pressure range 2.5-2.8 GPa.
