Book excerpt: The series of compounds (gadolinium, erbium, dysprosium)2-x, (manganese)y substituted samarium 2-x cobalt 17-y were studied with the object of developing permanent magnet materials having intrinsically temperature compensated magnetizations. The properties investigated were saturation magnetization, temperature coefficient of magnetization, and anisotropy field. The composition ranges studied were from x=0 to 0.6 and y=0 to 2. It was established that excellent temperature compensation could be achieved in these compounds in the temperature range -50 to 150 C. The systematic variations of saturation magnetization and anisotropy field with gadolinium, erbium and dysprosium concentation for fixed values of the manganese concentration will be discussed.
