Abstract
It is shown that the substitution of minute amounts of Cu for Be in TiBe 2 causes the susceptibility to increase monotonically. Magnetization data for TiBe2-xCux at 1.24 K and 4.17 K in fields up to 213 kOe are analysed in the Landau model of phase transitions. The critical concentration for ferromagnetism, xc, is about 0.2. Ag and Au as solutes decrease the susceptibility of TiBe2 (preliminary results). The magnetic moment of Fe in TiBe2-xFe x is estimated to be smaller than 0.01 μBKeywords
