High‐field magnetization studies were made from 4 °K to room temperature on rapidly sputtered TbFe2, DyFe2, and SmFe2. At 4.2 °K the magnetic moment resembles that of polycrystal samples, whereas at room temperature it is substantially lower. Huge coercive forces (20–30 kOe) were observed at 4.2 °K. Partial crystallization of TbFe2from the sputtered amorphous state yields high‐energy products and coercivities (> 3 kOe) at room temperature.
