Magnetic Compton profiles (MCPs) of DyCo 3B 2 and DyCo 4B have been measured at 10 K. From leastsquares fits with the Dy-4f and Co-3d atomic profiles, it is found that the Co-3d spin moment, which is antiparallel to the total magnetization, decreases with increasing the B concentration, while the Dy-4f and delocalized spin moments increase.
