We have observed superlattice reflections from the low-carrier system CeP under high pressures up to 2
GPa and also under magnetic field up to 12.5
T by means of synchrotron X-ray diffraction. The observed intensities of superlattice reflections are well explained by a model that takes into account both the lattice and charge modulation due to the periodic arrangement of ferromagnetic double layers of Γ
8-like Ce ions in the lattice of Γ
7 Ce ions. A new magnetic phase with the period of nine Ce planes was found in the experiment at the magnetic field of 12.5
T.
