High-field magnetization for the external field of up to 530 kOe at 4.2 K as well as temperature dependence of low-field susceptibility between 2 and 290 K have been measured on the magnetically ordered heavy-electron compound YbP. Except for the susceptibility at the lowest temperatures, the experimental data are found to be described quite well by the analyses in terms of both the single-site effects of the crystalline-electric-field (CEF) and the Kondo coupling of the Г6 doublet ground state of Yb3+ ion, and the interatomic exchange interaction with an antiferromagnetic coupling between the Г6 states. It is also shown that the temperature-independent susceptibility at the lowest temperatures is considered as a manifestation of the onset of magnetic correlations from well above the ordering temperature.
