Magnetoelastic properties of a single crystal of CeP have been investigated by magnetostriction and thermal expansion measurements. The longitudinal magnetostriction at 4.2 K shows an abrupt decrease in length around 0.5 T with a large hysteresis in the virgin cycle. Moreover, iso-field thermal expansion shows a large increase of the length at the temperature where the ferromagnetic-paramagnetic transition takes place. Such large length changes can be understood by the p-f mixing effect which has been used successfully to explain the magnetic phase diagram of CeP.
