The magnetization for the ferrimagnetic compounds Er 2 Co 17 , ErCo 6 , and Er 2 Co 7 has been studied in the temperature range 4.2 to 1250 °K and at field strengths up to 30 kOe. The Curie temperatures and the saturation magnetizations at 4.2 °K have been determined. For all compounds a maximum has been observed in the magnetization versus temperature curves. Er 2 Co 7 shows a compensation point at 140 °K. For this compound changes in the crystalline anisotropy were observed near the compensation point. The values of the coercive force obtained by mortar grinding samples of Er 2 Co 17 , ErCo 6 , Er 2 Co 7 , and ErCo 3 are compared with the variation of the lattice parameters for these compounds.
