Spin-wave and exchange stiffness constants of 22 ferromagnetic compounds have been deduced from their spontaneous magnetization, 
, by using an improved technique. The improvement consists in utilizing the entire 
curve, up to the Curie point, rather than just its low-temperature part, with 
. For 17 of the 22 ferromagnets, literature data have been used, while 5 compounds have been studied anew, on single crystals grown for the purpose.
