Recently, the compound Co/sub 5/Gd was shown to have antiferromagnetic coupling. The present work is on compounds of this type in which most of the rare earth elements were substituted for gadolinium and copper was substituted for some of the cobalt. The rare earth elements which have a high magnetic moment (gadolinium, terbium, dysprosium, holmium, erbium, thulium) have an effect on the magnetization vs temperature curve which is starting. The moment is greatly reduced in the vicinity of O deg K in the presence of one of these elements, in contrast to the high moment obtained when yttrium or a low-moment rare earth element (cerium, praseodymium, neodyrnium, samarium) ls present. As a result of these measurement, the magnetic structure of most of the compounds of cobalt with a rare earth element may be thought of as consisting of a sublattice of the rare earth with a magnetic moment ln oppositlon to that of the sublattice of the cobalt atoms. All of the compounds conform to thls plcture with reasonable accuracy except those whlch contain praseodyrnium and neodymium. In these two cases, the moment of the compounds is actually increased but the reason for this behavior was not determined. The presence of compensatlon points in the magnetization of some of these materials was demonstrated experimentally. (auth)
