  We have measured the X-ray absorption (XAS) and X-ray magnetic circular
dichroism (XMCD)at the Mn L3,2 edges in ferromagnetic Ga1-xMnxP for
0.018<x<0.042. Large XMCD asymmetries at the L3 edge indicate significant
spin-polarization of the density of states at the Fermi energy. The temperature
dependence of the XMCD and moment per Mn of 2.67 Bohr magnetons calculated
using sum rules are consistent with magnetometry values. The spectral shapes of
the XAS and XMCD are nearly identical with those for Ga1-xMnxAs indicating that
the hybridization of Mn d and anion p states is similar in the two materials.
