Measurements are presented of the nuclear resonance frequency of 59Co in (Fe1-xCox)2B ferromagnetic borides at 4.2K for 0.1<or=x<or=1 by using the spin echo technique. The measurements show that the average resonance frequency increases with the mean magnetization and this increase can be correlated with an increment of the magnetic moment on cobalt atoms. The origin of this increasing moment of cobalt is discussed; a transition from a state of weak ferromagnetism in pure Co 2B to a state of strong ferromagnetism with increasing iron content is the retained assumption. On the whole these results are in good agreement with a previous Mossbauer investigation, particularly in what concerns (i) the increasing of the magnetic moment on cobalt, (ii) the orientations of the easy magnetization direction and (iii) the short range character of the magnetic disturbance around iron atoms.
