The collapse of the Co moment in the ferrimagnetic Er1-xLuxCo2 compounds has been studied by means of magnetization, magnetostriction and 59Co spin echo measurements. The collapse of the Co moment is observed at the critical concentration around x = 0.3 in zero magnetic field. The application of a high magnetic field also induces the moment collapse in the compounds below the critical concentration, which is observed as a metamagnetic transition. From the metamagnetic transition field of ErCo2 observed at 52 T, the exchange constant between Er and Co can be estimated to be JErCo = - 1.3 × 10-22 J.
