Further measurements of the magnetic properties of some salts of the iron group at low temperatures

Abstract This paper is a continuation of the work reported in a former paper and contains measurements of the magnetization of MnSO 4 , MnJ 2 , MnF 2 , MnBr 2 , NiCl 2 , NiF 2 , Cr 2 (SO 4 ) 3 , CrCl 3 , CuF 2 and CuSO 4 at temperatures down to 14°K.
